referencing string

int mmap_string_ref(MMAPString * string);

int mmap_string_unref(char * str);
        

MMAPString provides a mechanism that let you use MMAPString like normal strings. You have first to use mmap_string_ref(), so that you notify that the string will be used as a normal string, then, you use mmapstr->str to refer to the string. When you have finished and you want to free a string corresponding to a MMAPString, you will use mmap_string_unref.

mmap_string_ref() references the string so that the array of characters can be used as a normal string then released with mmap_string_unref(). The array of characters will be obtained with string->str. returns -1 on error, 0 on success.

Structure that contains some standard fields and allows access to a given header without running through the list.

mailimf_fields is the native structure that IMF module will use, this module will provide an easier structure to use when parsing fields. mailimf_single_fields is an easier structure to get parsed fields, rather than iteration over the list of fields

• fld_orig_date is the parsed "Date" field (see the Section called mailimf_orig_date).

• fld_from is the parsed "From" field (see the Section called mailimf_from).

• fld_sender is the parsed "Sender "field (see the Section called mailimf_sender).

• reply_to is the parsed "Reply-To" field (see the Section called mailimf_reply_to).

• fld_to is the parsed "To" field (see the Section called mailimf_to).

• fld_cc is the parsed "Cc" field (see the Section called mailimf_cc).

• fld_bcc is the parsed "Bcc" field (see the Section called mailimf_bcc).

• fld_message_id is the parsed "Message-ID" field. (see the Section called mailimf_message_id).

• fld_in_reply_to is the parsed "In-Reply-To" field. (see the Section called mailimf_in_reply_to).

• fld_references is the parsed "References" field. (see the Section called mailimf_references).

• fld_subject is the parsed "Subject" field (see the Section called mailimf_subject).

• fld_comments is the parsed "Comments" field (see the Section called mailimf_comments).

• fld_keywords is the parsed "Keywords" field (see the Section called mailimf_keywords).

mailimf_single_fields_new() creates and initializes a data structure with a value. Structures given as argument are referenced by the created object and will NOT be freed if the object is released.

mailimf_single_fields_free() frees memory used by the structure and substructures will NOT be released. They should be released by the application.

mailimf_single_fields_init() will initialize fill the data structure, using the given argument (fields). The interesting fields will be filled into single_fields.

Header fields

int mailimf_envelope_fields_write(FILE * f, int * col,

int mailimf_field_write(FILE * f, int * col,
    struct mailimf_field * field);
        

• col current column is given for wrapping purpose in (* col), the resulting columns will be returned..

• f is the file descriptor. It can be stdout for example.

• fields is the header fields (see the Section called mailimf_fields).

• field is a field (see the Section called mailimf_field).

mailimf_fields_write outputs the set of header fields.

mailimf_envelope_fields_write outputs the set of header fields except the optional fields.

mailimf_field_write outputs a header.
