pthread_cond_signal(2) OSS System Calls Reference Manual
To use this function in a 32-bit threaded application that uses the POSIX User Thread Model
library on systems running H06.24 or later RVUs or J06.13 or later RVUs, perform the same
tasks (described above) used to enable the POSIX User Thread Model library on systems running
H06.21/J06.10 or later RVUs.
To use this function in a 64-bit threaded application that uses the POSIX User Thread Model
library on systems running H06.24 or later RVUs or J06.13 or later RVUs, you must perform all
of the following tasks:
• Include the pthread.h header file in the application.
• Compile the application using the _PUT_MODEL_ feature test macro or equivalent
compiler command option.
• Compile the application using the -Wlp64 compiler command option.
• Link the application to the yputdll library (/G/system/zdllnnn/yputdll).
To use this function in a threaded application that uses the Standard POSIX Threads library on
systems running H06.21 or later RVUs or J06.10 or later RVUs, you must perform all of the fol-
lowing tasks:
• Include the spthread.h header file in the application.
• Compile the application using the _SPT_MODEL_ feature test macro or equivalent
compiler command option.
• Link the application to the zsptdll library (/G/system/zdllnnn/zsptdll).
RETURN VALUES
If an error condition occurs, this function returns an integer value indicating the type of error.
Possible return values are:
0 Successful completion.
[EINVAL] The value specified by the cond parameter is not a valid condition variable.
[ENOMEM] There is insufficient memory to perform the requested operation.
RELATED INFORMATION
Functions: pthread_cond_broadcast(2), pthread_cond_destroy(2), pthread_cond_init(2),
pthread_cond_timedwait(2), pthread_cond_wait(2).
STANDARDS CONFORMANCE
Interfaces documented on this reference page conform to the following industry standards:
• IEEE Std 1003.1-2004, POSIX System Application Program Interface
The use of the header file spthread.h is an HP exception to the POSIX standard.
The return of [ENOMEM] is an HP extension to the POSIX standard.
