QlgMkfifo()--Make FIFO Special File (using NLS-enabled path name)
Syntax
#include <sys/types.h>
#include <sys/stat.h>
#include <Qlg.h>
int QlgMkfifo(const Qlg_Path_Name_T *path,
mode_t mode);
Service Program Name: QP0LLIB1Default Public Authority: *USE
Threadsafe: Conditional; see Usage Notes for mkfifo().
The QlgMkfifo() function, like the mkfifo() function, creates a new FIFO special file whose name is defined by path. The difference is that the QlgMkfifo() function takes a pointer to a Qlg_Path_Name_T structure, while mkfifo() takes a pointer to a character string.
Limited information on the path parameter is provided here. For more information on the path parameter and for a discussion of other parameters, authorities required, return values, and related information, see mkfifo()--Make FIFO Special File.
Parameters
- path
- (Input) A pointer to a Qlg_Path_Name_T structure that contains a path name or a pointer to a path name of the FIFO to be created. For more information on the Qlg_Path_Name_T structure, see Path name format.
