Name
ustrtol - 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);
