Format
#include <string.h>
char *strcpy(char *string1, const char *string2);Language Level: ANSI
Threadsafe: Yes.
Description
The strcpy() function copies string2, including the ending null character, to the location that is specified by string1.
The strcpy() function operates on null-ended strings. The string arguments to the function should contain a null character (\0) that marks the end of the string. No length checking is performed. You should not use a literal string for a string1 value, although string2 may be a literal string.
Return Value
The strcpy() function returns a pointer to the copied string (string1).
Example that uses strcpy()
This example copies the contents of source to destination.
#include <stdio.h>
#include <string.h>
#define SIZE 40
int main(void)
{
char source[SIZE] = "This is the source string";
char destination[SIZE] = "And this is the destination string";
char * return_string;
printf( "destination is originally = \"%s\"\n", destination );
return_string = strcpy( destination, source );
printf( "After strcpy, destination becomes \"%s\"\n", destination );
}
/***************** Output should be similar to: *****************
destination is originally = "And this is the destination string"
After strcpy, destination becomes "This is the source string"
