ANSI_SYNOPSIS
|
|
#include <stdio.h>
|
|
void perror(char *<[prefix]>);
|
|
|
|
void _perror_r(struct _reent *<[reent]>, char *<[prefix]>);
|
|
|
|
TRAD_SYNOPSIS
|
|
#include <stdio.h>
|
|
void perror(<[prefix]>)
|
|
char *<[prefix]>;
|
|
|
|
void _perror_r(<[reent]>, <[prefix]>)
|
|
struct _reent *<[reent]>;
|
|
char *<[prefix]>;
|
|
|
|
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>>.
