Function Documentation

◆ db_char2op()

db_op_t db_char2op ( const char c )

Give a single char, translate it to a db_op_t. If it does not correspond to a known operator, DB_OP_NULL is returned

◆ db_str2op()

db_op_t db_str2op ( const char * str )

Get the next CSG boolean operator found in a given string.

Skipping any whitespace, this routine returns the CSG boolean operation in canonical (single-byte enumeration) form. It will attempt to recognize operators in various unicode formats if the input string contains mixed encodings.
