FUNCTION
|
|
<<strerror_r>>---convert error number to string and copy to buffer
|
|
|
|
INDEX
|
|
strerror_r
|
|
|
|
ANSI_SYNOPSIS
|
|
#include <string.h>
|
|
char *strerror_r(int <[errnum]>, char *<[buffer]>, size_t <[n]>);
|
|
|
|
TRAD_SYNOPSIS
|
|
#include <string.h>
|
|
char *strerror_r(<[errnum]>, <[buffer]>, <[n]>)
|
|
int <[errnum]>;
|
|
char *<[buffer]>;
|
|
size_t <[n]>;
|
|
|
|
DESCRIPTION
|
|
<<strerror_r>> converts the error number <[errnum]> into a
|
|
string and copies the result into the supplied <[buffer]> for
|
|
a length up to <[n]>, including the NUL terminator. The value of
|
|
<[errnum]> is usually a copy of <<errno>>. If <<errnum>> is not a known
|
|
error number, the result is the empty string.
|
|
|
|
See <<strerror>> for how strings are mapped to <<errnum>>.
|
|
|
|
RETURNS
|
|
This function returns a pointer to a string. Your application must
|
|
not modify that string.
|
|
|
|
PORTABILITY
|
|
<<strerror_r>> is a GNU extension.
|
|
|
|
<<strerror_r>> requires no supporting OS subroutines.
