## Functions

### GMimeParserWarningFunc ()

    void
    (*GMimeParserWarningFunc) (gint64 offset,
                               GMimeParserWarning errcode,
                               const gchar *item,
                               gpointer user_data);

The function signature for a callback to `g_mime_parser_options_set_warning_callback()`.

#### Parameters

offset | parser offset where the issue has been detected, or -1 if it is unknown |
errcode | a GMimeParserWarning |
item | a NUL-terminated string containing the value causing the issue, may be `NULL` |
user_data | User-supplied callback data. |

### g_mime_parser_options_new ()

    GMimeParserOptions *
    g_mime_parser_options_new (void);

Creates a new set of GMimeParserOptions.

#### Returns

a newly allocated set of GMimeParserOptions with the default values.

### g_mime_parser_options_free ()

    void
    g_mime_parser_options_free (GMimeParserOptions *options);

Frees a set of GMimeParserOptions.

#### Parameters

options | a GMimeParserOptions |

### g_mime_parser_options_clone ()

    GMimeParserOptions *
    g_mime_parser_options_clone (GMimeParserOptions *options);

Clones a GMimeParserOptions.

#### Parameters

options | a GMimeParserOptions or `NULL`. | [nullable]

#### Returns

a newly allocated GMimeParserOptions.

[transfer full]

### g_mime_parser_options_get_default ()

    GMimeParserOptions *
    g_mime_parser_options_get_default (void);

Gets the default parser options.

#### Returns

the default parser options.

### g_mime_parser_options_get_address_compliance_mode ()

    GMimeRfcComplianceMode
    g_mime_parser_options_get_address_compliance_mode
                                   (GMimeParserOptions *options);

Gets the compliance mode that should be used when parsing rfc822 addresses.

Note: Even in GMIME_RFC_COMPLIANCE_STRICT mode, the address parser is fairly liberal in what it accepts. Setting it to GMIME_RFC_COMPLIANCE_LOOSE just makes it try harder to deal with garbage input.

#### Parameters

options | a GMimeParserOptions or `NULL`. | [nullable]

#### Returns

the compliance mode that is currently set.

### g_mime_parser_options_set_address_compliance_mode ()

    void
    g_mime_parser_options_set_address_compliance_mode
                                   (GMimeParserOptions *options,
                                    GMimeRfcComplianceMode mode);

Sets the compliance mode that should be used when parsing rfc822 addresses.

In general, you'll probably want this value to be GMIME_RFC_COMPLIANCE_LOOSE (the default) as it allows maximum interoperability with existing (broken) mail clients and other mail software such as sloppily written perl scripts (aka spambots).

Note: Even in GMIME_RFC_COMPLIANCE_STRICT mode, the address parser is fairly liberal in what it accepts. Setting it to GMIME_RFC_COMPLIANCE_LOOSE just makes it try harder to deal with garbage input.

#### Parameters

options | a GMimeParserOptions |
mode | a GMimeRfcComplianceMode |

### g_mime_parser_options_get_allow_addresses_without_domain ()

    gboolean
    g_mime_parser_options_get_allow_addresses_without_domain
                                   (GMimeParserOptions *options);

Gets whether or not the rfc822 address parser should allow addresses without a domain.

In general, you'll probably want this value to be `FALSE` (the default) as it allows maximum interoperability with existing (broken) mail clients and other mail software such as sloppily written perl scripts (aka spambots) that do not properly quote the name when it contains a comma.

This option exists in order to allow parsing of mailbox addresses that do not have a domain component. These types of addresses are rare and were typically only used when sending mail to other users on the same UNIX system.

#### Parameters

options | a GMimeParserOptions or `NULL`. | [nullable]

#### Returns

`TRUE` if the address parser should allow addresses without a domain.

### g_mime_parser_options_set_allow_addresses_without_domain ()

    void
    g_mime_parser_options_set_allow_addresses_without_domain
                                   (GMimeParserOptions *options,
                                    gboolean allow);

Sets whether the rfc822 address parser should allow addresses without a domain.

In general, you'll probably want this value to be `FALSE` (the default) as it allows maximum interoperability with existing (broken) mail clients and other mail software such as sloppily written perl scripts (aka spambots) that do not properly quote the name when it contains a comma.

This option exists in order to allow parsing of mailbox addresses that do not have a domain component. These types of addresses are rare and were typically only used when sending mail to other users on the same UNIX system.

#### Parameters

options | a GMimeParserOptions |
allow | `TRUE` if the parser should allow addresses without a domain or `FALSE` otherwise |

### g_mime_parser_options_get_parameter_compliance_mode ()

    GMimeRfcComplianceMode
    g_mime_parser_options_get_parameter_compliance_mode
                                   (GMimeParserOptions *options);

Gets the compliance mode that should be used when parsing Content-Type and Content-Disposition parameters.

Note: Even in GMIME_RFC_COMPLIANCE_STRICT mode, the parameter parser is fairly liberal in what it accepts. Setting it to GMIME_RFC_COMPLIANCE_LOOSE just makes it try harder to deal with garbage input.

#### Parameters

options | a GMimeParserOptions or `NULL`. | [nullable]

#### Returns

the compliance mode that is currently set.

### g_mime_parser_options_set_parameter_compliance_mode ()

    void
    g_mime_parser_options_set_parameter_compliance_mode
                                   (GMimeParserOptions *options,
                                    GMimeRfcComplianceMode mode);

Sets the compliance mode that should be used when parsing Content-Type and Content-Disposition parameters.

In general, you'll probably want this value to be GMIME_RFC_COMPLIANCE_LOOSE (the default) as it allows maximum interoperability with existing (broken) mail clients and other mail software such as sloppily written perl scripts (aka spambots).

Note: Even in GMIME_RFC_COMPLIANCE_STRICT mode, the parameter parser is fairly liberal in what it accepts. Setting it to GMIME_RFC_COMPLIANCE_LOOSE just makes it try harder to deal with garbage input.

#### Parameters

options | a GMimeParserOptions |
mode | a GMimeRfcComplianceMode |

### g_mime_parser_options_get_rfc2047_compliance_mode ()

    GMimeRfcComplianceMode

                                   (GMimeParserOptions *options);

Gets the compliance mode that should be used when parsing rfc2047 encoded words.

Note: Even in GMIME_RFC_COMPLIANCE_STRICT mode, the rfc2047 parser is fairly liberal in what it accepts. Setting it to GMIME_RFC_COMPLIANCE_LOOSE just makes it try harder to deal with garbage input.

#### Parameters

options | a GMimeParserOptions or `NULL`. | [nullable]

#### Returns

the compliance mode that is currently set.

### g_mime_parser_options_set_rfc2047_compliance_mode ()

Sets the compliance mode that should be used when parsing rfc2047 encoded words.

In general, you'll probably want this value to be GMIME_RFC_COMPLIANCE_LOOSE (the default) as it allows maximum interoperability with existing (broken) mail clients and other mail software such as sloppily written perl scripts (aka spambots).

Note: Even in GMIME_RFC_COMPLIANCE_STRICT mode, the parameter parser is fairly liberal in what it accepts. Setting it to GMIME_RFC_COMPLIANCE_LOOSE just makes it try harder to deal with garbage input.
