NAME
explain_execvp_or_die - execute a file and report errors SYNOPSIS
#include <libexplain/execvp.h> void explain_execvp_or_die(const char *pathname, char *const *argv); DESCRIPTION

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. SEE ALSO
