Fvselinit, Fvselinit32(3fml)
Name
Fvselinit(), Fvselinit32() - initialize structure element to null
Synopsis
#include <stdio.h>
#include "fml.h"
int
Fvselinit(char *cstruct, char *cname, char *view)
#include "fml32.h"
int
Fvselinit32(char *cstruct, char *cname, char *view)
Description
Fvselinit() initializes an individual element of a C structure to its appropriate null value. cstruct is a pointer to a C structure. cname is a pointer to the name of an element of cstruct. view is a pointer to the name of a compiled view description.
Fvselinit() sets the associated count member of the element to 0 if the C flag was used when the view was compiled, and sets the associated length member to the length of the associated null value if the L flag was used in the view file.
Fvselinit32() is used for views defined with viewc32 or VIEW32 typed buffers for larger views with more fields.
A thread in a multithreaded application may issue a call to Fvselinit() or Fvselinit32() while running in any context state, including TPINVALIDCONTEXT.
Return Values
This function returns -1 on error and sets Ferror to indicate the error condition.
Errors
Under the following conditions, Fvselinit() fails and sets Ferror to:
One of the arguments to the function invoked was invalid (for example, specifying a NULL cstruct parameter invalid Fvselinit).
The view description specified was NULL or was not found in the files specified by VIEWDIR or VIEWFILES.
The C structure field name is not found in the view description.
