explain_mount_or_die(3) Library Functions Manual explain_mount_or_die(3) NAME explain_mount_or_die - mount file system and report errors SYNOPSIS #include <libexplain/mount.h> void explain_mount_or_die(const char *source, const char *target, const char *file_systems_type, unsigned long flags, const void *data); int explain_mount_on_error(const char *source, const char *target, const char *file_systems_type, unsigned long flags, const void *data); DESCRIPTION The explain_mount_or_die function is used to call the mount(2) system call. On failure an explanation will be printed to stderr, obtained from the ex- plain_mount(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_mount_on_error function is used to call the mount(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_mount(3) function, but still returns to the caller. source The source, exactly as to be passed to the mount(2) system call. target The target, exactly as to be passed to the mount(2) system call. file_systems_type The file_systems_type, exactly as to be passed to the mount(2) sys- tem call. flags The flags, exactly as to be passed to the mount(2) system call. data The data, exactly as to be passed to the mount(2) system call. RETURN VALUE The explain_mount_or_die function only returns on success, see mount(2) for more information. On failure, prints an explanation and exits, it does not return. The explain_mount_on_error function always returns the value return by the wrapped mount(2) system call. EXAMPLE The explain_mount_or_die function is intended to be used in a fashion simi- lar to the following example: explain_mount_or_die(source, target, file_systems_type, flags, data); SEE ALSO mount(2) mount file system explain_mount(3) explain mount(2) errors exit(2) terminate the calling process COPYRIGHT libexplain version 1.3 Copyright (C) 2013 Peter Miller explain_mount_or_die(3)
