Návod, kniha: POSIX Programmer's Manual

STRUČNĚ

#include <string.h> char *strcat(char *restrict s1, const char *restrict s2);

POPIS / INSTRUKCE

The strcat() function shall append a copy of the string pointed to by s2 (including the terminating null byte) to the end of the string pointed to by s1. The initial byte of s2 overwrites the null byte at the end of s1. If copying takes place between objects that overlap, the behavior is undefined.

NÁVRATOVÁ HODNOTA

The strcat() function shall return s1; no return value is reserved to indicate an error.

CHYBY / ERRORY

No errors are defined. The following sections are informative.

PŘÍKLADY POUŽITÍ

APPLICATION USAGE

This issue is aligned with the ISO C standard; this does not affect compatibility with XPG3 applications. Reliable error detection by this function was never guaranteed.

RATIONALE
