# uoffset(3alleg4)

Finds the offset of a character in a string. Allegro game programming library.

## 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.
