NAME Cif_Memmode - Selects the memory management mode for a com- piler information file (CIF) SYNOPSIS #define CIF_VERSION 2 #include <cif.h> int Cif_Memmode (cifd, mode) int cifd; int mode; IMPLEMENTATION All Sun SPARC systems DESCRIPTION The Cif_Memmode routine establishes the memory management mode that processes the structures that the Cif_Getrecord(3) routine returns. The Cif_Memmode routine accepts the following arguments: cifd Specifies CIF descriptor returned by the Cif_Open(3) routine. mode Specifies memory managment mode. You can specify one of the following three modes for mode: CIF_MEM_INDIV Each structure is returned by using newly allocated space. You must free the space when it is no longer needed. You can use the Cif_Free(3) routine to free individual structures. CIF_MEM_FIXED Each call to Cif_Getrecord uses the same memory area. The next call to Cif_Getrecord overwrites the contents of the memory area. This is the default mode. CIF_MEM_MANAGED Structures are allocated from memory that the library routines manage. Structures are accumulated as they are encountered and can be released by using the Cif_Release(3) routine. Cif_Memmode must be called after the Cif_Open(3) routine, but before the first call to Cif_Getrecord, for any particu- lar CIF. Each open CIF can use a different mode. CIF_VERSION defines the library version. The default is 1. The newest version is 2 and should be used with this rou- tine. See the Cif(3) man page for a discussion about CIF informa- tion, format, and versions. RETURN VALUES A positive return value indicates successful completion. A negative return value indicates that an error occurred. EXAMPLES The following example, when used in a program, sets the memory management mode for the CIF that is identified by the descriptor mycif to CIF_MEM_INDIV. The descriptor is assigned by the Cif_Open routine. int mycif; . . . (void) Cif_Memmode (mycif, CIF_MEM_INDIV); . . .
