QlgMkfifo()--Make FIFO Special File (using NLS-enabled path name)

 #include <sys/types.h>
 #include <sys/stat.h>
 #include <Qlg.h>

 int QlgMkfifo(const Qlg_Path_Name_T *path,  
              mode_t mode);  

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.

Example

See Code disclaimer information for information pertaining to code examples.

The following example creates a new FIFO:

#include <sys/stat.h>
#include <stdio.h>
#include <string.h>
#include <Qlg.h>

void main()
{
 typedef struct pnstruct
    {
     Qlg_Path_Name_T qlg_struct;
     char[100] pn;  /* This size must be >= the path */
                              /* name length or a pointer to   */
                              /* the path name.                */
    };
 struct pnstruct path;

 char *mypath = "/newFIFO";

 /**************************************************************/
 /*   Initialize Qlg_Path_Name_T structure.                    */
 /**************************************************************/
 memset((void*)path name, 0x00, sizeof(struct pnstruct));
 path.qlg_struct.CCSID = 37;
 memcpy(path.qlg_struct.Country_ID, "US", 2);
 memcpy(path.qlg_struct.Language_ID, "ENU", 3);
 path.qlg_struct.Path_Type = QLG_CHAR_SINGLE;
 path.qlg_struct.Path_Length = strlen(mypath);
 path.qlg_struct.Path_Name_Delimiter = '/';
 memcpy(path.pn, mypath, strlen(mypath));

 if (QlgMkfifo((Qlg_Path_Name_T *)path name,
               S_IRWXU|S_IRWXO) != 0)
   perror("QlgMkfifo() error");
 else
   puts("success!");

 return;
