This is different from the semaphore\'s _value_, which is set when the semaphore is opened and changed with signal() and wait()\. .sp The point of semaphores is that you don\'t care how many users are using the resource; you merely wait on a semaphore until the resource becomes available or you give up\. When you\'re done, you signal it and off you go\. .sp Back to the open count\. FT_NWSEMLOCK() opens the semaphore as named in <cSemaphore>\. After it is opened, the open count is checked\. If it is anything other than 1, that means someone else has it (or you failed in your open) so the semaphore is closed and the "lock" is refused\. If the value is 1, then your app is that 1 station so the "lock" is granted\. .sp You can use a semaphore lock to control access to anything that Clipper\'s RLOCK() and FLOCK() can\'t help you with, such as text files written with the low level file i/o functions, etc\. .sp .in 0.08i \fBExamples .sp .in 0.4i .br IF FT_NWSEMLOCK( "k:\\apps\\error\.log" ) .in 0.72i .br // Note, you aren\'t actually LOCKING this file, you are .br // just locking a semaphore by the same name\.

PASS IT BY REFERENCE! .br .ta .sp \fB<@nOpenCnt>\fR is the number of stations that have opened the semaphore\. THIS MUST BE PASSED BY REFERENCE! On exit, \fB<nOpenCnt> will contain a numeric value\. .sp .in 0.08i \fBReturns .sp .in 0.48i nRc, a numeric result code, as follows: .sp .in 0.96i .br 0 - success .in 0.8i .br 254 - Invalid semaphore name length .br 255 - Invalid semaphore value .sp .in 0.48i <nHandle> will contain the semaphore handle, and <nOpenCnt> will contain the number of stations that have opened the semaphore\. .sp .in 0.08i \fBDescription .sp .in 0.48i A semaphore is simply a label that indirectly controls network activity\. There is a semaphore name, which can be up to 127 characters, and an associated value, which can range from 0 to 127\. .sp A semaphore can be used for many things, but is most often used to limit the number of users in an application, and to control access to a network resource\. .sp A semaphore essentially allows you to place locks on resources other than files\. .sp An application begins the process by calling FT_NWSEMOPEN()\. If the semaphore doesn\'t exist, NetWare will create it\. FT_NWSEMOPEN() returns a handle that is used in other semaphore calls\. .sp Applications use FT_NWSEMWAIT() to wait for a semaphore to become available\. FT_NWSEMWAIT() decrements the semaphore\'s value by 1\. If the value > 0, then the application should be allowed to access the semaphore\'s resource\. If the value goes negative, then the application is placed in a queue\. How long your app is in the queue is determined by how you set the timeout parameter\. If you can\'t get the resource in the time you allot, you\'re let out of the queue and the value increments by 1 again\. .sp When an application finishes with a semaphore, it should call FT_NWSEMSIG() to increment the value, and then FT_NWSEMCLOSE() to close the semaphore\. When the semaphore\'s open count goes to 0, NetWare deletes it\. .sp FT_NWSEMEX() can be used to examine the value and open count without affecting them\. .sp For an interesting discussion on the operating system aspects of semaphores, check "Operating Systems Design and Implementation" by A\. Tanenbaum, page 60\. For more details on NetWare\'s semaphore facilities, refer to Charles Rose\'s "Programmer\'s Guide to NetWare"\.
