This is an easy exercise. You'll find an example in K&R, here is my
version. (Of course, the function should be included into the libc.a.)
#include <strings.h> /* strlen(), include a prototype for strdup here */
#include <stdlib.h> /* malloc() */
char *
strdup(const char *src)
{
char *rv;
register char *dst;
if(rv = dst = (char *)malloc(strlen(src) + 1))
while(*dst++ = *src++) /* hmmm... */ ;
return rv;
}
