NAME
explain_execve_or_die - execute program and report errorsSYNOPSIS
#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.
