NAME

TrivBzrTVReadFromFile2()

SYNOPSIS

prsr_lib/trivread.c:379

TrivTVStruct *TrivBspTVReadFromFile2(int Handler,
                                     CagdBType NameWasRead,
                                     char **ErrStr,
                                     int *ErrLine)

DESCRIPTION

Reads from a file a Bezier trivariate. If NameWasRead is TRUE, it is assumed prefix "[TRIVAR 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 trivariate. If no error is detected *ErrStr is set to NULL.

PARAMETERS:

Handler: A handler to the open stream.

NameWasRead: If FALSE, also reads the TRIVAR BEZIER prefix.

ErrStr: Will be initialized if an error has occured.

ErrLine: Line number in file FileName of the error, if occured.

FUNCTION RETURN VALUE

TrivTVStruct *: The read trivariate, or NULL if an error occured.
