shmdt
SHMDT(P) POSIX Programmer's Manual SHMDT(P) NAME
shmdt - XSI shared memory detach operation SYNOPSIS
#include <sys/shm.h> int shmdt(const void *shmaddr); DESCRIPTION
The shmdt() function operates on XSI shared memory (see the Base Definitions volume of IEEE Std 1003.1-2001, Section 3.340, Shared Memory Object). It is unspecified whether this function interoperates with the realtime interprocess communication facilities defined in Realtime . The shmdt() function detaches the shared memory segment located at the address specified by shmaddr from the address space of the calling process. RETURN VALUE
Upon successful completion, shmdt() shall decrement the value of shm_nattch in the data structure associated with the shared memory ID of the attached shared memory segment and return 0. Otherwise, the shared memory segment shall not be detached, shmdt() shall return -1, and errno shall be set to indicate the error. ERRORS
The shmdt() function shall fail if: EINVAL The value of shmaddr is not the data segment start address of a shared memory segment. The following sections are informative. EXAMPLES
None. APPLICATION USAGE
The POSIX Realtime Extension defines alternative interfaces for interprocess communication. Application developers who need to use IPC should design their applications so that modules using the IPC routines described in XSI Interprocess Communication can be easily modified to use the alternative interfaces. RATIONALE
None. FUTURE DIRECTIONS
None. SEE ALSO
