◆ geometry_type_from_string()

int geometry_type_from_string ( const char *  str,
uint8_t type,
int *  z,
int *  m 
)

Calculate type integer and dimensional flags from string input.

Utility function to get type number from string.

Case insensitive, and insensitive to spaces at front and back. Type == 0 in the case of the string "GEOMETRY" or "GEOGRAPHY". Return LW_SUCCESS for success.
