STRDUP(3)                 OpenBSD Programmer's Manual                STRDUP(3)

NAME
     strdup - save a copy of a string



SYNOPSIS
     #include <string.h>

     char *
     strdup(const char *s);

DESCRIPTION
     The strdup() function allocates sufficient memory for a copy of the
     string s, does the copy, and returns a pointer to it.  The pointer may
     subsequently be used as an argument to the function free(3).

     If insufficient memory is available, NULL is returned.

EXAMPLES
     The following will point p to an allocated area of memory containing the
     null-terminated string "foobar":

           char *p;

           p = strdup("foobar");

     free(3),  malloc(3),  strcpy(3),  strlen(3)

HISTORY
     The strdup() function first appeared in 4.4BSD.
