NAME¶

error_temp - identify soft syscall error codes

SYNTAX¶

#include <error.h>

int error_temp(e);

int e;

error_temp returns 1 if syscall error code e is a soft error, 0 if it is a hard error. Normally e is errno.

A hard error is persistent: file not found, read-only file system, symbolic link loop, etc.

A soft error is usually transient: out of memory, out of disk space, I/O error, disk quota exceeded, connection refused, host unreachable, etc.
