ustrtol(3) Allegro manual ustrtol(3)NAMEustrtol - Converts a string into an integer. Allegro game programming
library.
SYNOPSIS
#include <allegro.h>
long ustrtol(const char *s, char **endp, int base);
DESCRIPTION
This function converts the initial part of `s' to a signed integer,
setting `*endp' to point to the first unused character, if `endp' is
not a NULL pointer. The `base' argument indicates what base the digits
(or letters) should be treated as. If `base' is zero, the base is
determined by looking for `0x', `0X', or `0' as the first part of the
string, and sets the base used to 16, 16, or 8 if it finds one. The
default base is 10 if none of those prefixes are found. Example:
char *endp, *string = "456.203 askdfg";
int number = ustrtol(string, &endp, 10);
RETURN VALUE
Returns the string converted as a value of type `long int'. If nothing
was converted, returns zero with `*endp' pointing to the beginning of
`s'.
