NAME

explain_execvp_or_die - execute a file and report errors

SYNOPSIS

void explain_execvp_or_die(const char *pathname, char *const *argv);

DESCRIPTION

The explain_execvp_or_die function is used to call the execvp(3) system call. On failure an explanation will be printed to stderr, obtained from explain_execvp(3), and then the process terminates by calling exit(EXIT_FAILURE).

This function is intended to be used in a fashion similar to the following example:

explain_execvp_or_die(pathname, argv);

pathname: The pathname, exactly as to be passed to the execvp(3) system call.
argv: The argv, exactly as to be passed to the execvp(3) system call.
Returns:: This function only returns on success. On failure, prints an explanation and exits.
