MQ_GETSETATTR(2) Linux Programmer's Manual MQ_GETSETATTR(2)
mq_getsetattr - get/set message queue attributes
#include <sys/types.h> #include <mqueue.h> int mq_getsetattr(mqd_t mqdes, struct mq_attr *newattr, struct mq_attr *oldattr); Note: There is no glibc wrapper for this system call; see NOTES.
Do not use this system call. This is the low-level system call used to implement mq_getattr(3) and mq_setattr(3). For an explanation of how this system call operates, see the description of mq_setattr(3).
This interface is nonstandard; avoid its use.
Glibc does not provide a wrapper for this system call; call it using syscall(2). (Actually, never call it unless you are writing a C library!)
