NAME
BspCrvReadFromFile2()
SYNOPSIS
prsr_lib/bsp_read.c:95
CagdCrvStruct *BspCrvReadFromFile2(int Handler,
CagdBType NameWasRead,
char **ErrStr,
int *ErrLine)
DESCRIPTION
Reads from a file a Bspline curve.
If NameWasRead is TRUE, it is assumed prefix "[CURVE BSPLINE" has
already been read. This is useful for a global parser which invokes this
routine to read from a file several times as a parent controller.
For exactly this reason, the given file descriptor is NOT closed in the
end.
If error is found in reading the file, ErrStr is set to a string
describing it and ErrLine to line it occured in file relative to begining
of curve.
If no error is detected *ErrStr is set to NULL.
PARAMETERS:
Handler: A handler to the open stream.
NameWasRead: TRUE if "[CURVE BSPLINE" has been read, FALSE otherwise.
ErrStr: Will be initialized if an error has occured.
ErrLine: Line number in file FileName of the error, if occured.
FUNCTION RETURN VALUE
CagdCrvStruct *: The read curve, or NULL if an error occured.
