NAME

xt_strcat() - Concatenate strings without risk of buffer overflow

LIBRARY

#include <xtend/string.h>
-lxtend

SYNOPSIS

size_t  xt_strlcat(char *dest, const char *src, size_t dstsize)

ARGUMENTS

dest:   Pointer to a character array of at least len dstsize, where
the possibly modified string is stored.
src:    Point to a character array containing the string to compact
dstsize: Length of the dest array

DESCRIPTION

Concatenate string src to dest, truncating if necessary to avoid overflowing the destination array.

RETURN VALUES

The combined lengths of the two strings. If the return value is larger than the dstsize, then truncation has occurred.

EXAMPLES

#define MAXLEN  127
char    limited_str[MAXLEN + 1],


        original_str[SOME_OTHER_LEN + 1];
xt_strlcat(limited_str, original_str, MAXLEN + 1);
