"~" is a shortcut that shells (like bash) implement. At the "C" api level, you can only use actual relative or absolute paths (no environment variables or anything).
If you wish to implement functionality similar to "~" you must do something like:
Code:
#include <pwd.h>
.
.
struct passwd *pwd=getpwuid(getuid());
if(pwd && pwd->pw_dir) {
    execl("/usr/bin/find","find",pwd->pw_dir,"-name","filename.c",0);
} else {
    fprintf(stderr,"Cannot find home directory\n");
}
