NAME

explain_execve_or_die - execute program and report errors

SYNOPSIS

void explain_execve_or_die(const char *pathname, const char *const *argv, const char *const *envp);

DESCRIPTION

The explain_execve_or_die function is used to call the execve(2) system call. On failure an explanation will be printed to stderr, obtained from explain_execve(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_execve_or_die(pathname, argv, envp);

pathname: The pathname, exactly as to be passed to the execve(2) system call.
argv: The argv, exactly as to be passed to the execve(2) system call.
envp: The envp, exactly as to be passed to the execve(2) system call.
Returns:: This function only returns on success. On failure, prints an explanation and exits.
