Function Documentation

Gj_Path * Gj_path_new ( )

Create a new path structure. Calls to Gj_path_init() and Gj_path_finalize() are not needed.

Gj_Path * Gj_path_create ( Gj_Ctx * ctx, Gj_Stream * stream )

Create a path structure from a stream. Returns: The pointer to the path on success, 0 otherwise.

int Gj_path_read ( Gj_Ctx * ctx, Gj_Path * path, Gj_Stream * stream )

Read a path form a stream. Returns: 0 on success, -1 otherwise.

int Gj_path_write ( Gj_Ctx * ctx, Gj_Path * path, Gj_Stream * stream )

Write a path to a stream. Returns: 0 on success, -1 otherwise.

void gj_path_addElem ( Gj_Path * path, gj_Pathelem * elem )

Add a path element to the end of the path list. For internal use only.

void Gj_path_addString ( Gj_Path * path, char * str )

Add a string path element. The string is DUPLICATED.

Gj_PathType Gj_path_nextType ( Gj_Path * path, void ** ptr )

Return the type of the next element of the walkthrough. If *ptr is 0, the type of the first element is returned. If the last element has already been reached, GJ_PATHTYPE_NONE is returned. Calls to Gj_path_nextType do not change the walkthrough position.

char * Gj_path_nextAsString ( Gj_Path * path, void ** ptr )

Return the next element of a walkthrough as a string. If *ptr is 0, the first element is returned. If the last element has already been reached, 0 is returned.

Gj_Id * Gj_path_nextAsId ( Gj_Path * path, void ** ptr )

Return the next element of a walkthrough as an id. If *ptr is 0, the first element is returned. If the last element has already been reached, 0 is returned.

int * Gj_path_nextAsNum ( Gj_Path * path, void ** ptr )

Return the next element of a walkthrough as a pointer to a number. If *ptr is 0, the first element is returned. If the last element has already been reached, 0 is returned.
