## NAME

ustrncpy - Copies a string into another one, specifying size. Allegro game programming library.

## SYNOPSIS

**#include \<allegro.h\>**

**char \*ustrncpy(char \*dest, const char \*src, int n);**

## DESCRIPTION

This function is like ustrcpy() except that no more than \`n' characters from \`src' are copied into \`dest'. If \`src' is shorter than \`n' characters, null characters are appended to \`dest' as padding until \`n' characters have been written.

Note that if \`src' is longer than \`n' characters, \`dest' will not be null-terminated.

## RETURN VALUE
