_CP_read

_CP_read is equivalent to the read, readu and readu locked BASIC statements (depending upon type):

Type	BASIC Statement
_CP_READ	read result from expression,string
_CP_READU	readu result from expression,string
_CP_READUL	readu result from expression,string locked value = 0 else value = 1 If value is not needed, the user can pass (int*) 0.

Syntax

int _CP_read(int type, CPSTR** result, int expression, CPSTR* string, int* value)

The _CP_read call uses the same optimized read routine as BASIC, which is faster than using AQL and BASIC. The expression should be an integer file descriptor returned by the _CP_open call.

Description

This function returns -1 if an error occurs. The error code is contained in _CP_errno.

Example(s)

/* Reads the item "myid" from "myfile". */

CPSTR * s = _CP_mkstr("myfile");

CPSTR * id = _CP_mkstr("myid");

CPSTR * xx = _CP_str_null;

int f;

_CP_open(&f,_CP_str_null,s);

_CP_read(_CP_READ, &xx, f, id, 0);
