Usually SOAP functions return this value in a variable named syserror, which is meaningful only when the function return value, usually called iReturnValue, indicate an error (that is, have a value of -1 or -100, depending of the case).
- Parameters:
-
[in] | errnum | : Error number |
[out] | Response |
- sArray : See the description below.
- sResponse.iReturnValue : Return value
- 0 : success
- -1: system error (see syserrno).
- sResponse.syserrno : System-error code. The value of the libc "errno" code, see MXCommon__Strerror().

STRERROR(3)
NAME
strerror, strerror_r - return string describing error code
SYNOPSIS
#include <string.h>
char *strerror(int errnum);
#define _XOPEN_SOURCE 600
#include <string.h>
int strerror_r(int errnum, char *buf, size_t n);
DESCRIPTION
The strerror() function returns a string describing the error code passed
in the argument errnum,possibly using the LC_MESSAGES part of the current
locale to select the appropriate language.
This string must not be modified by the application, but may be modified
by a subsequent call to perror() or strerror(). No library function will
modify this string.
The strerror_r() function is similar to strerror(), but is thread safe.
It returns the string in the user-supplied buffer buf of length n.
RETURN VALUE
The strerror() function returns the appropriate error description string,
or an unknown error message if the error code is unknown.
The value of errno is not changed for a successful call, and is set to a non-zero
value upon error.
The strerror_r() function returns 0 on success and -1 on failure, setting errno.
ERRORS
EINVAL The value of errnum is not a valid error number.
ERANGE Insufficient storage was supplied to contain the error description string.
CONFORMING TO
SVID 3, POSIX, 4.3BSD, ISO/IEC 9899:1990 (C89).
strerror_r() with prototype as given above is specified by SUSv3,
and was in use under Digital Unix and HP Unix. An incompatible function,
with prototype
char *strerror_r(int errnum, char *buf, size_t n);
is a GNU extension used by glibc (since 2.0), and must be regarded as obsolete
in view of SUSv3.
The GNU version may, but need not, use the user-supplied buffer.
If it does, the result may be truncated in case the supplied buffer is too small.
The result is always NUL-terminated.
