14 shm_open \- open a shared memory object
26 The \fBshm_open()\fR function establishes a connection between a shared memory
28 to the shared memory object and a file descriptor that refers to that open file
30 shared memory object. The \fIname\fR argument points to a string naming a
31 shared memory object. It is unspecified whether the name appears in the file
40 If successful, \fBshm_open()\fR returns a file descriptor for the shared memory
81 If the shared memory object exists, this flag has no effect, except as noted
82 under \fBO_EXCL\fR below. Otherwise the shared memory object is created; the
83 user \fBID\fR of the shared memory object will be set to the effective user
84 \fBID\fR of the process; the group \fBID\fR of the shared memory object will be
86 the process. The permission bits of the shared memory object will be set to the
90 affect whether the shared memory object is opened for reading, for writing, or
91 for both. The shared memory object has a size of zero.
100 If \fBO_EXCL\fR and \fBO_CREAT\fR are set, \fBshm_open()\fR fails if the shared
101 memory object exists. The check for the existence of the shared memory object
103 other processes executing \fBshm_open()\fR naming the same shared memory object
114 If the shared memory object exists, and it is successfully opened \fBO_RDWR\fR,
122 When a shared memory object is created, the state of the shared memory object,
123 including all data associated with the shared memory object, persists until the
124 shared memory object is unlinked and all other references are gone. It is
125 unspecified whether the name and shared memory object state remain valid after
131 non-negative integer representing the lowest numbered unused file descriptor.
144 The shared memory object exists and the permissions specified by \fIoflag\fR
145 are denied, or the shared memory object does not exist and permission to create
146 the shared memory object is denied, or \fBO_TRUNC\fR is specified and write
156 \fBO_CREAT\fR and \fBO_EXCL\fR are set and the named shared memory object
204 Too many shared memory objects are currently open in the system.
213 \fBO_CREAT\fR is not set and the named shared memory object does not exist.
222 There is insufficient space for the creation of the new shared memory object.
