The following functions provide an interface to extract and manipulate these references.

Function
po_filepos_t po_message_filepos (po_message_t message, int index)
Returns the file reference in position index from the message. If index is out of range, returns NULL.
Function
void po_message_remove_filepos (po_message_t message, int index)
Removes the file reference in position index from the message. It moves all references following index one position backwards.
Function
void po_message_add_filepos (po_message_t message, const char *file, size_t start_line)
Adds a reference to the string from file starting at start_line, if it is not already present for the message. The value (size_t)(-1) for start_line denotes that the line number is not available.
