disable_hardware_cursor – Disables the OS hardware cursor. Allegro game programming library. Synopsis#include <allegro.h> void disable_hardware_cursor(void); DescriptionAfter calling this function, Allegro will be responsible for drawing the mouse cursor rather than the operating system. On some platforms calling enable_hardware_cursor() makes the return values of get_mouse_mickeys() unreliable. After calling this function, get_mouse_mickeys() returns reliable results again. See…

basename, dirname – parse pathname components Synopsis#include <libgen.h> char *dirname(char *path); char *basename(char *path);DescriptionWarning: there are two different functions basename() – see below. The functions dirname() and basename() break a null-terminated pathname string into directory and filename components. In the usual case, dirname() returns the string up to, but not including, the final ‘/’, and…

dirfilename — retrieve the name of a dirfile Synopsis#include <getdata.h> const char *dirfilename(const DIRFILE *dirfile);DescriptionThe dirfilename() function queries a dirfile(5) database specified by dirfile and returns its name. The name of a dirfile is the pathname passed to dirfile_cbopen() or dirfile_open() when the dirfile was opened. The dirfile argument must point to a valid DIRFILE…

dirfile_validate — check a dirfile field code for validity Synopsis#include <getdata.h> int dirfile_validate(DIRFILE *dirfile, const char *field_code);DescriptionThe dirfile_validate() function queries a dirfile(5) database specified by dirfile and checks whether field_code, which may contain a representation suffix, specifies a valid field. The dirfile argument must point to a valid DIRFILE object previously created by a call…

dirfile_uninclude — remove a format file fragment from a dirfile Synopsis#include <getdata.h> int *dirfile_uninclude(DIRFILE *dirfile, int fragment_index, int del);DescriptionThe dirfile_uninclude() removes the format file fragment indexed by fragment_index from the specified dirfile, as well as any fragments the specified fragment INCLUDEs. Fields defined in the removed fragments will be removed from the dirfile. Before removing…

dirfile_rename — change the name of a dirfile field Synopsis#include <getdata.h> int dirfile_rename(DIRFILE *dirfile, const char *old_code, const char *new_name, int move_data);DescriptionThe dirfile_rename() function changes the name of the field specified by old_code, which should not contain a representation suffix, defined in the dirfile specified by dirfile to new_name. If the new name is the…

dirfile_reference, get_reference — retrieve or set the reference field for a dirfile Synopsis#include <getdata.h> const char *dirfile_reference(DIRFILE *dirfile, const char *field_code); const char *get_reference(DIRFILE *dirfile);DescriptionThe dirfile_reference() function sets or retrieves the reference field (see dirfile(5)) associated with the dirfile specified by dirfile. If the field_code argument is non-NULL, the reference field for the dirfile will…

dirfile_protect — modify the protection level of a dirfile fragment Synopsis#include <getdata.h> int dirfile_protect(DIRFILE *dirfile, int protection_level, int fragment_index);DescriptionThe dirfile_protect() function sets the advisory protection level of the format file fragment specified by fragment_index to protection_level in the dirfile(5) database specified by dirfile. The protection_level argument should be one of the following: GD_PROTECT_NONE Indicating that…

dirfile_parser_callback — set the syntax error callback handler for a dirfile Synopsis#include <getdata.h> void dirfile_parser_callback(DIRFILE *dirfile, gd_parser_callback_t sehandler, void *extra);DescriptionThe dirfile_parser_callback() updates the syntax error callback function of the DIRFILE object dirfile to be sehandler, and the caller supplied extra pointer passed to the handler to be extra, discarding any syntax error handler and extra…

dirfile_cbopen, dirfile_open — open or create a dirfile Synopsis#include <getdata.h> DIRFILE* dirfile_cbopen(const char *dirfilename, unsigned long flags, gd_parser_callback_t sehandler, void *extra); DIRFILE* dirfile_open(const char *dirfilename, unsigned long flags);DescriptionThe dirfile_cbopen() function opens or creates the dirfile specified by dirfilename, returning a DIRFILE object associated with it. Opening a dirfile will cause the library to read and…

dirfile_move — move a dirfile field between format file fragments Synopsis#include <getdata.h> int dirfile_move(DIRFILE *dirfile, const char *field_code, int new_fragment, int move_data);DescriptionThe dirfile_move() function transfers the field specified by field_code, which should not have a representation suffix, defined in the dirfile specified by dirfile from it’s current format file fragment to the fragment index by…

dirfile_metaflush — close a dirfile and free associated memory. Synopsis#include <getdata.h> int dirfile_metaflush(DIRFILE *dirfile);DescriptionThe dirfile_metaflush() function flushes all pending metadata changes in the dirfile specified by dirfile to disk. This is accomplished by re-writing the format file fragments containing modified metadata. Format file fragments which are unchanged are not touched. This function flushes only metadata….

dirfile_alter_spec, dirfile_malter_spec — modify a field in a dirfile Synopsis#include <getdata.h> int dirfile_alter_spec(DIRFILE *dirfile, const char *line, int recode); int dirfile_malter_spec(DIRFILE *dirfile, const char *line, const char *parent, int recode);DescriptionThe dirfile_alter_spec() function modifies the field described by the field specification line in line to the dirfile specified by dirfile. The dirfile_malter_spec() function behaves similarly, but…
