Fvsinit(), Fvsinit32() - initialize C structure to null
Fvsinit(char *cstruct, char *view)
Fvsinit32(char *cstruct, char *view)
Fvsinit() initializes all members in a C structure to the null values specified in the view description, view. cstruct is a pointer to a C structure. view is a pointer to a compiled view description.
Fvsinit() sets the associated count member of an 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.
Fvsinit32() 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 Fvsinit() or Fvsinit32() while running in any context state, including TPINVALIDCONTEXT.
This function returns -1 on error and sets Ferror to indicate the error condition.
Under the following conditions, Fvsinit() fails and sets Ferror to:
One of the arguments to the function invoked was invalid (for example, specifying a NULL cstruct parameter invalid Fvsinit()).
The view description specified was NULL or was not found in the files specified by VIEWDIR or VIEWFILES.
