The Pth 1.4.1 manual states that system() is supported in the
"Soft System Call Mapping", but in fact it is omitted (as an
oversight, I think).
Build Pth with --enable-syscall-soft, then compile this test
program with -E to show the preprocessed code:
#include "pthread.h"
#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>
int main() {
const char* msg = "... calling write() explicitly\n";
pthread_t dummy = pthread_self();
int rc = system("/bin/echo jls");
fprintf(stderr,"... after system call, rc %d\n", rc);
write(2, msg, strlen(msg));
}
You'll see that write has become __pthread_write, but system
is still system.
The fixes are to pthread.h.in:
