NAME¶
uoffset - Finds the offset of a character in a string. Allegro game programming
library.
SYNOPSIS¶
#include <allegro.h>
int uoffset(const char *s, int index);
DESCRIPTION¶
Finds out the offset (in bytes from the start of the string) of the character at
the specified `index' in the string `s'. A zero `index' parameter will return
the first character of the string. If `index' is negative, it counts backward
from the end of the string, so an `index' of `-1' will return an offset to the
last character. Example:
int from_third_letter = uoffset(text_string, 2);
RETURN VALUE¶
Returns the offset in bytes to the specified character.
