getcndxmem

Get memory required to process and store conditional index expressions (allows the proper memory allocation routines to be used on the client and server sides).

Declaration

pTEXT getcndxmem( UINT sizobj );

Description

The macros getcndxmem() and putcndxmem(), used to get and put memory required to process and store conditional index expressions, allow the proper memory allocation routines to be used on the client and server sides. (These substitute for the internal mballc() and mbfree() calls.)

Return Values

getcndxmem() returns a pointer to the newly allocated object on success. A NULL pointer is returned if memory could not be allocated.

Example

/* Allocate a run-time stack for the expression analyzer (first time only). */

if (!ctcidxStk) {

ctcidxStk = (pVOID) getcndxmem(CNDX_MAX_STACK * ctSIZE(PLEAF));

if (!ctcidxStk) {

printf("Unable to allocate memory for run-time stack.\n");

ctrt_exit(1);

}

}

if (ctcidxStk)

putcndxmem(ctcidxStk);
