Example:

Description:

req4c_get_error_num() returns the error number set by the last req4c function call. Every req4c function call with the exception of req4c_get_error_num() and req4c_get_error_msg() clears both req4c error_num and req4c_error_msg

Bugs/Features/Comments:

req4c_get_error_num() does not access the network

req4c_get_error_num() leaves the current message list intact and does not reset $_REQ4C['errno'] or $_REQ4C['errmsg']

The superglobal $_REQ4C['errno'] also holds this error num
