14
16 Raises an assert for an error at the specified file and line number.
17 The file parameter is always given in ASCII format. By default, this
18 will call the system driver's assert handler. If there is none, the
19 error will be sent to stderr and the program will abort. However, if
20 the environment variable ALLEGRO_ASSERT is set, this function writes a
21 message into the file specified by the environment variable and program
22 execution will continue. If none of this behaviours is wanted, you can
23 override them with a custom assert handler.
24
25 You will usually want to use the ASSERT() macro instead of calling this
26 function directly.
