Data Type: po_message_t; This is a pointer type that refers to a message of a PO file, including its translation.

Function: po_message_t po_message_create (void); Returns a freshly constructed message. To finish initializing the message, you must set the msgid and msgstr. It must be inserted into a file to manage its memory, as there is no po_message_free available to the user of the library.

The following functions access details of a po_message_t. Recall that the results are valid as long as the file handle is valid.

Function: const char * po_message_msgctxt (po_message_t message); The po_message_msgctxt function returns the msgctxt, the context of message. Returns NULL for a message not restricted to a context.

Function: void po_message_set_msgctxt (po_message_t message, const char *msgctxt); The po_message_set_msgctxt function changes the msgctxt, the context of the message, to the value provided through msgctxt. The value NULL removes the restriction.

Function: const char * po_message_msgid (po_message_t message); The po_message_msgid function returns the msgid (untranslated English string) of message. This is guaranteed to be non-NULL.

Function: void po_message_set_msgid (po_message_t message, const char *msgid); The po_message_set_msgid function changes the msgid (untranslated English string) of message to the value provided through msgid, a non-NULL string.

Function: const char * po_message_msgid_plural (po_message_t message); The po_message_msgid_plural function returns the msgid_plural (untranslated English plural string) of message, a message with plurals, or NULL for a message without plural.

Function: void po_message_set_msgid_plural (po_message_t message, const char *msgid_plural); The po_message_set_msgid_plural function changes the msgid_plural (untranslated English plural string) of a message to the value provided through msgid_plural, or removes the plurals if NULL is provided as msgid_plural.

Function: const char * po_message_msgstr (po_message_t message); The po_message_msgstr function returns the msgstr (translation) of message. For an untranslated message, the return value is an empty string.

Function: void po_message_set_msgstr (po_message_t message, const char *msgstr); The po_message_set_msgstr function changes the msgstr (translation) of message to the value provided through msgstr, a non-NULL string.

Function: const char * po_message_msgstr_plural (po_message_t message, int index); The po_message_msgstr_plural function returns the msgstr[index] of message, a message with plurals, or NULL when the index is out of range or for a message without plural.

Function: void po_message_set_msgstr_plural (po_message_t message, int index, const char *msgstr_plural); The po_message_set_msgstr_plural function changes the msgstr[index] of message, a message with plurals, to the value provided through msgstr_plural. message must be a message with plurals. Use NULL as the value of msgstr_plural with index pointing to the last element to reduce the number of plural forms.

Function: const char * po_message_comments (po_message_t message); The po_message_comments function returns the comments of message, a multiline string, ending in a newline, or a non-NULL empty string.

Function: void po_message_set_comments (po_message_t message, const char *comments); The po_message_set_comments function changes the comments of message to the value comments, a multiline string, ending in a newline, or a non-NULL empty string.

Function: const char * po_message_extracted_comments (po_message_t message); The po_message_extracted_comments function returns the extracted comments of message, a multiline string, ending in a newline, or a non-NULL empty string.

Function: void po_message_set_extracted_comments (po_message_t message, const char *extracted_comments); The po_message_set_extracted_comments function changes the comments of message to the value extracted_comments, a multiline string, ending in a newline, or a non-NULL empty string.

Function: const char * po_message_prev_msgctxt (po_message_t message); The po_message_prev_msgctxt function returns the previous msgctxt, the previous context of message. Return NULL for a message that does not have a previous context.

Function: void po_message_set_prev_msgctxt (po_message_t message, const char *prev_msgctxt); The po_message_set_prev_msgctxt function changes the previous msgctxt, the context of the message, to the value provided through prev_msgctxt. The value NULL removes the stored previous msgctxt.

Function: const char * po_message_prev_msgid (po_message_t message); The po_message_prev_msgid function returns the previous msgid (untranslated English string) of message, or NULL if there is no previous msgid stored.
