Create and throw errors easily
With clib
$ clib install jwerle/throw.h
#include "throw.h"
int
main (void) {
error_t eperm = error_new(EPERM, "EPERM");
error_t enoent = error_new(ENOENT, "ENOENT");
error_t esrch = error_new(ESRCH, "ESRCH");
error_t eintr = error_new(EINTR, "EINTR");
throw(&eperm, "Operation not permitted");
throw(&enoent, "No such file or directory");
throw(&esrch, "No such process");
throw(&eintr, "Interrupted system call");
return 0;
}
You can also set the stream where errors are written to by defining the THROW_FD file descriptor.
THROW_FD = stderr; // or some other `FILE *` pointer
