sem_init
sem_init(2) System Calls Manual sem_init(2)NAME
sem_init - initialize an unnamed POSIX semaphore
SYNOPSIS DESCRIPTION
is used to initialize an unnamed semaphore. A successful call to will create a new unnamed semaphore referred to by sem, if one does not
exist, initialize the unnamed semaphore descriptor, referred to by sem, to the non-negative value specified by value. If the unnamed sema-
phore already exists, i.e. created by a previous call to it is re-initialized only if its current value is equal to its initial value (set
by the last successful call to If so, the initial value of the unnamed semaphore is re-initialized to the value argument. Otherwise, the
call fails.
The argument pshared specifies if the unnamed semaphore is sharable with other processes. If pshared is equal to 0, the unnamed semaphore
is not shared with other processes. If pshared is non-zero, the unnamed semaphore is sharable with any processes that can access sem. The
access mode specified for the unnamed semaphore allows read and write permissions to all processes. If the calling process may attach to
the shared structure, it is assumed it may operate on the semaphore.
To use this function, link in the realtime library by specifying on the compiler or linker command line.
EXAMPLES
The following call to will create a new unnamed semaphore referred to by sem, if one does not exist, initialize the unnamed semaphore
descriptor, referred to by sem, to the non-negative value specified by value.
RETURN VALUE
If the semaphore was created and initialized, returns 0 to the caller.
If the semaphore could not be created/initialized, the call returns -1 and sets to indicate the error.
ERRORS
fails and does not perform the requested operation if any of the following conditions are encountered:
[EPERM] The calling process does not have the privileges necessary to initialize the semaphore.
[EBUSY] There are threads currently blocked on the semaphore or there are outstanding locks held on the semaphore.
[EINVAL] The argument value is greater than
[ENOSPC] There are insufficient resources to perform the operation or the upper limit on the number of semaphores is reached.
