ustrerror(3alleg4) Allegro manual ustrerror(3alleg4)

ustrerror - Returns a string describing errno. Allegro game programming library.

#include <allegro.h>

const char *ustrerror(int err);

This function returns a string that describes the error code `err', which normally comes from the variable `errno'. Example:


PACKFILE *input_file = pack_fopen("badname", "r");
if (input_file == NULL)
allegro_message("%s\nSorry!\n", ustrerror(errno));

Returns a pointer to a static string that should not be modified or freed. If you make subsequent calls to ustrerror(), the string will be overwritten.
