# ustrzncat(3alleg4)

Concatenates a string to another one, specifying size. Allegro game programming library.

## NAME

ustrzncat - Concatenates a string to another one, specifying size. Allegro game programming library.

## SYNOPSIS

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

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

## DESCRIPTION

This function is like ustrzcat() except that no more than \`n' characters from \`src' are appended to the end of \`dest'. If the terminating null character in \`src' is reached before \`n' characters have been written, the null character is copied, but no other characters are written. Note that \`dest' is guaranteed to be null-terminated.

## RETURN VALUE

The return value is the value of \`dest'.
