msgctl(2) System Calls Manual msgctl(2)
NAME
msgctl() - message control operations
SYNOPSIS
DESCRIPTION
provides a variety of message control operations as specified by cmd. The following cmds are available:
Place the current value of each member of the data structure associated with
msqid into the structure pointed to by buf. The contents of this structure are defined in glossary(9). This command
requres the privilege to operate on a message queue not permitted by access modes. This command requires the privi-
lege to operate on a message queue in a different compartment.
Set the value of the following members of the data structure associated with
msqid to the corresponding value found in the structure pointed to by buf:
This cmd can only be executed by a process that has the privilege or has an effective user ID equal to the value of
either or in the data structure associated with msqid. Only a user with the privilege can raise the value of
WARNING: Programs compiled on HP-UX revisions prior to HP-UX 11i v1 use old 16-bit msqid_ds structure fields
(obtained via which can describe queue sizes only up to 64 KBytes. Care must be taken such that queues shared with
such programs are not made larger than 64 KBytes(65535). Or, those existing programs should be recompiled. Or, the
system administrator should restrict the kernel tunable parameter to 64 KBytes or less.
Remove the message queue identifier specified by
msqid from the system and destroy the message queue and data structure associated with it. This cmd can only be exe-
cuted by a process that has the privilege or has an effective user ID equal to the value of either or in the data
structure associated with msqid.
Security Restrictions
Some or all of the actions associated with this system call are subject to compartmental restrictions. See compartments(5) for more infor-
mation about compartmentalization on systems that support that feature.
Compartmental restrictions can be overridden if the process possesses the privilege (PRIV_COMMALLOWED). Processes owned by the superuser
may not have this privilege. Processes owned by any user may have this privilege, depending on system configuration.
Some or all of the actions associated with this system call require the or privileges (PRIV_DACREAD, PRIV_LIMIT or PRIV_OWNER). Processes
owned by the superuser have these privileges. Processes owned by other users may have one or more of these privileges, depending on system
configuration.
See privileges(5) for more information about privileged access on systems that support fine-grained privileges.
RETURN VALUE
Upon successful completion, a value of 0 is returned. Otherwise, a value of -1 is returned and is set to indicate the error.
ERRORS
fails if one or more of the following is true:
msqid is not a valid message queue identifier.
cmd is not a valid command, or the command contains invalid parameters.
cmd is equal to and Read operation permission is denied to the calling process (see message operation permissions in glos-
sary(9)).
cmd is equal to or and the calling process does not have the privilege or the effective user ID of the calling process is not
equal to the value of either or in the data structure associated with msqid.
cmd is equal to an attempt is being made to increase to the value of and the user does not have the privilege.
buf points to an illegal address. Reliable detection of this error is implementation dependent.
