(prsr_lib/cagdread.c:192)

Prototype:

CagdSrfStruct *CagdSrfReadFromFile2(int Handler, char **ErrStr, int *ErrLine)

Description:

Reads from a stream a surface. It is assumed prefix "[SURFACE" has already been read. This is useful for a global parser which invokes this routine to read from a stream several times as a parent controller. For exactly this reason, the given stream descriptor is NOT closed in the end. If error is found in reading the stream, ErrStr is set to a string describing it and ErrLine to line it occured in stream relative to begining of surface. If no error is detected *ErrStr is set to NULL.

Parameters:

Handler:	A handler to the open stream.
ErrStr:	Will be initialized if an error has occured.
ErrLine:	Line number in stream of the error, if occured.

Returned Value:

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