explain_execve_or_die — execute program and report errors

Synopsis

#include <libexplain/execve.h>

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.
