strcpy - copy a string


#include <string.h>

char *strcpy(char *s1, const char *s2);


The strcpy() function copies the string pointed to by s2 (including the terminating null byte) into the array pointed to by s1. If copying takes place between objects that overlap, the behaviour is undefined.


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


No errors are defined.




Character movement is performed differently in different implementations. Thus overlapping moves may yield surprises.

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.
