Type |
Description |
nError |
SHORT |
Error number. |
pszMsg |
PSTR |
Buffer to the returned error string. |
nErrorMaxLen |
SHORT |
The size of the error string buffer. |
pnStatus |
PSHORT |
Returned status: 0 on success, negative number on failure. |
The function returns the error string associated with the nError as returned from other driver functions.
The following table displays the possible error values; not all errors apply to this board type:

The following example initializes the board. If the initialization failed, the following error string is printed:
CHAR sz[256];
SHORT nStatus, nHandle;
..
Gx5642Initialize (3, &Handle, &Status);
if (nStatus<0)
{ GxPioGetErrorString(nStatus, sz, sizeof sz, &nStatus);
printf(sz); // prints the error string returns
}
