size_t ULSqlcaBase::GetParameter(
ul_u_long parm_num,
char * buffer,
size_t size
)
parm_num A 1-based parameter number.
buffer The buffer to receive parameter string.
size The size, in chars, of the buffer.
Gets the error parameter string.
The output parameter string is always null-terminated, even if the buffer is too small and the parameter is truncated. The parameter number is 1-based.
If the function succeeds, the return value is the buffer size required to hold the entire parameter string.
If the function fails, the return value is zero. The function fails if an invalid (out of range) parameter number is given.
