void _perror_r(struct _reent *<[reent]>, char *<[prefix]>);
import newlib-2000-02-17 snapshot
2000-02-18 03:39:52 +08:00
DESCRIPTION
Use <<perror>> to print (on standard error) an error message
corresponding to the current value of the global variable <<errno>>.
Unless you use <<NULL>> as the value of the argument <[prefix]>, the
error message will begin with the string at <[prefix]>, followed by a
colon and a space (<<: >>). The remainder of the error message is one
of the strings described for <<strerror>>.
The alternate function <<_perror_r>> is a reentrant version. The
extra argument <[reent]> is a pointer to a reentrancy structure.
RETURNS
<<perror>> returns no result.
PORTABILITY
ANSI C requires <<perror>>, but the strings issued vary from one
implementation to another.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
