#include <fcntl.h> int QlgCreat64(Qlg_Path_Name_T *path,mode_t mode);Service Program Name: QP0LLIB1
The QlgCreat64() function, like the creat64() function, creates a new file or rewrites an existing file so that it is truncated to zero length. The difference is that the QlgCreat64() function takes a pointer to a Qlg_Path_Name_T structure, while creat64() takes a pointer to a character string. See creat64()--Create or Rewrite a File (Large File Enabled) and open64()--Open File (Large File Enabled) for more details on how the function call
QlgCreat64(path,mode);is equivalent to the call
QlgOpen64(path, O_CREAT|O_WRONLY|O_TRUNC, mode);
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 creat64()--Create or Rewrite a File (Large File Enabled) or open64()--Open File (Large File Enabled).
See Code disclaimer information for information pertaining to code examples.
The following example creates a file:
#define _LARGE_FILE_API #include <stdio.h> #include <fcntl.h> #include <Qp0lstdi.h> main() { char text[]="This is a test"; int fd; #define mypath "creat.file" const char US_const[3]= "US"; const char Language_const[4] ="ENU"; typedef struct pnstruct { Qlg_Path_Name_T qlg_struct; char pn[100]; /* This array size must be >= the */ /* length of the path name or this must */ /* be a pointer to the path name. */ }; struct pnstruct path; /*****************************************************************/ /* Initialize Qlg_Path_Name_T parameters */ /*****************************************************************/ memset((void*)&path, 0x00, sizeof(struct pnstruct)); path.qlg_struct.CCSID = 37; memcpy(path.qlg_struct.Country_ID,US_const,2); memcpy(path.qlg_struct.Language_ID,Language_const,3); path.qlg_struct.Path_Type = QLG_CHAR_SINGLE; path.qlg_struct.Path_Length = sizeof(mypath)-1; path.qlg_struct.Path_Name_Delimiter[0] = '/'; memcpy(path.pn,mypath,sizeof(mypath)-1); if ((fd = QlgCreat64( (Qlg_Path_Name_T *)&path, S_IRUSR | S_IWUSR)) < 0) { perror("QlgCreat64() error"); } else { write(fd, text, strlen(text)); close(fd); QlgUnlink((Qlg_Path_Name_T *)&path); } }
