Function Documentation

strcat()

char* strcat	(	char *	s1,
		const char *	s2
	)

Concatenates two strings.

Parameters

*s1	Destination string
*s2	String to be appended

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

Note

If there is no null character in the first n characters of the array pointed to by s2, the result will not be null-terminated.

Copying between overlapping objects is supported, but the source may be overwritten.

Returns

The value of s1
