CEEOPXI
C library interface: pthread_mutexattr_init(), pthread_rwlockattr_init()
CEEOPXI initializes the mutex attributes or read-write lock attributes object specified by attr_object. Upon successful completion of this function, the attributes object is set to this implementation's default. For attribute values, see CEEOPXS.
Syntax
void CEEOPXI (attr_object, lock_type,
[fc])
CEE_LOCKATTR *attr_object;
INT4 *lock_type;
FEED_BACK *fc;- CEEOPXI
- Call this CWI interface as follows:
L R15,CEECAALEOV-CEECAA(,R12) CAA address is in R12 L R15,0324(,R15) BALR R14,R15 - attr_object (input)
- The caller-provided attributes object.
- lock_type (input)
- A full word integer with the following defined values:
- X'00000000' = mutex
- X'00000001' = read-write lock
- fc (output/optional)
- The feedback code returned by the service. It indicates the degree of success in initializing the new attributes object.
The following message identifiers and associated severities can be returned by the service in the feedback code fc.
