SpStdQueryLength returns the number of data bytes in the PM_Q_STD buffer identified by hstd.
Syntax
SplStdQueryLength(hstd)
Parameters
- hstd (HSTD) - input
- The handle to the PM_Q_STD buffer.
Return Code
- rc (LONG) - returns
- Return codes.
This function returns the size of hstd (cBytes) or SPL_ERROR, if an error occurred.
#include <os2.h> HSTD hstd; /* The handle to the PM_Q_STD buffer. */ LONG rc; /* Return codes. */ rc = SplStdQueryLength(hstd);
