NAME

BzrSrfReadFromFile2()  

SYNOPSIS

prsr_lib/bzr_read.c:282

CagdSrfStruct *BzrSrfReadFromFile2(int Handler,
                                   CagdBType NameWasRead,
                                   char **ErrStr,
                                   int *ErrLine)
 

DESCRIPTION

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

PARAMETERS:

Handler: A handler to the open stream.

NameWasRead: TRUE if "[SURFACE BEZIER" hasbeen 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

CagdSrfStruct *: The read surface, or NULL if an error occured.
