int getFMTypeCode ( char * begin,
char ** end,
int4 * type )
 

Get the geoobj type from the string.

getFMTypeCode: Parses the object type from the input character string "begin", placing the integer value in type. The double character pointer is set to the space following the "type" name -- suitable for passing to a later parser for the numbers. On error, the variable 'type' is set to zero. The function returns the value of 'type', so zero means failure -- which you should check!
