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 viewfile.

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.
