Function _conLastError() Foundation

Determines the error code of the last operation.

Syntax
XPPAPIRET _conLastError();
Return

The function returns an error code (XPP_ERR_...).

Description

_conLastError() is used to determine the error code for functions that return no error code. These are the functions for creating containers (_conNew...()) and for modifying containers (_conPut...()). When no error has occurred during the last called function, the return value of _conLastError() is undefined.

Examples
/* 
 Produces an array with 2 x 5000 elements and determines the error if 
the operation fails. 
*/ 
#include <xppcon.h> 

ContainerHandle  hArray; 
XPPAPIRET        xr; 


hArray = _conNewArray(2, 2, 5000); 
if (hArray == NULLCONTAINER) 
{ 
 xr = _conLastError(); 
 /* ... error handling */ 
} 
else 
{ 
 /* ... operations with the array container */ 

 _conRelease(hNew); 
}
