siad_getgrent(3) Library Functions Manual siad_getgrent(3) NAME siad_getgrent, siad_getgrgid, siad_getgrnam, siad_setgrent, siad_end- grent - group routines for SIA (Security Integration Architecture) LIBRARY Standard C library (libc.so and libc.a) SYNOPSIS #include <sia.h> #include <siad.h> int siad_getgrent( struct group *result, char *buffer, int buflen, FILE **context); int siad_getgrgid( gid_t gid, struct group *result, char *buffer, int buflen); int siad_getgrnam( char *name, struct group *result, char *buffer, int buflen); int siad_setgrent( FILE **context); int siad_endgrent( FILE **context); PARAMETERS result The result parameter is used to provide a result. The actual result string is placed in the buffer provided and result points to the resultant struct group in the buffer. Values in the passwd structure may be changed by the siad_*gr* rou- tines. buffer The buffer parameter is a pointer to a buffer which holds the resultant struct group. This parameter is read only. buflen The buflen parameter is the length of the buffer in chars. This parameter are read only. gid The gid parameter is the group identifier (GID) for the re- quest. This parameter are read only. name The name parameter specifies the group name for the request. This parameter are read only. context A pointer to the location that records which I/O stream is to be used. DESCRIPTION siad_getgrent() The siad_getgrent routine is called indirectly (by the sia_switch func- tion) from the sia_getgroup() routine which is called from the libc and libc_r routines getgrent() and getgrent_r() respectively. The buffer for the group information is preallocated and a thread lock has been taken in the thread safe mode. siad_getgrgid() This routine is called indirectly (by the sia_switch function) from the sia_getgroup() routine which is called from the libc and libc_r rou- tines getgrgid and getgrgid_r respectively. The buffer for the group information is preallocated and a thread lock has been taken in the thread safe mode. siad_getgrnam() This routine is called indirectly (by the sia_switch function) from the sia_getgroup() routine which is called from the libc and libc_r rou- tines getgrnam and getgrnam_r respectively. The buffer for the group information is preallocated and a thread lock has been taken in the thread safe mode. siad_setgrent() This routine is called by the sia_getgroup() routine to start or ini- tialize a series of getgrent calls. siad_endgrent() This routine is called to close or complete the processing of a get- grent() series of calls. RETURN VALUES The siad_*gr*() routines return bitmapped values which indicate the following status: SIADSUCCESS Indicates unconditional success. All bits set to 0. SIADFAIL Indicates conditional failure. Lowest bit set to 1. If other security mechanism are in place, continue. SIADSTOP Indicates unconditional failure. Do not continue. Sec- ond lowest bit set to 1. ERRORS The errno values are those returned from the dynamic loader interface, from the (siad_*) routines, or from malloc. Possible errors include resource constraints (no memory) and various authentication failures.
