explain_execv_or_die3
Execute a file and report errors
Usage
#include <libexplain/execv.h>
void explain_execv_or_die(const char *pathname, char *const*argv);
int explain_execv_on_error(const char *pathname, char *const*argv);
Overview
The explain_execv_or_die function is used to call the execv(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_execv(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_execv_on_error function is used to call the execv(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_execv(3) function, but still returns to the caller.
pathname
|
The pathname, exactly as to be passed to the execv(3) system call. |
|---|---|
argv
|
The argv, exactly as to be passed to the execv(3) system call. |
Return value
The explain_execv_or_die function only returns on success, see execv(3) for more information. On failure, prints an explanation and exits, it does not return.
The explain_execv_on_error function always returns the value return by the wrapped execv(3) system call.
Examples
The explain_execv_or_die function is intended to be used in a fashion similar to the following example:
explain_execv_or_die(pathname, argv);Releases
