strdup

Returns a pointer to a null-terminated byte string, which is a duplicate of the string pointed to by src . The space for the new string is obtained as if the malloc was invoked. The returned pointer must be passed to free to avoid a memory leak.

If an error occurs, a null pointer is returned and errno might be set.

Parameters

Return value

A pointer to the newly allocated string, or a null pointer if an error occurred.

Notes

The function is identical to the POSIX strdup .

Example

#include <string.h>
#include <stdio.h>
#include <stdlib.h>
 
int main(void)
{
    const char *s1 = "Duplicate me!";
    char *s2 = strdup(s1);
    printf("s2 = \"%s\"\n", s2);
    free(s2);
}

s2 = "Duplicate me!"
