Standard POSIX Threads Functions: Differences
Between the Previous and Current Standards
Open System Services Porting Guide—520573-006

Changed Thread Functions
Changed Thread Functions
This subsection lists the thread functions in groups according to differences between
the following two standards:
•
The IEEE 1003.1c standard, 1995. (Standard POSIX Threads adheres to this
standard, officially listed as International Standard ISO/IEC 9945-1; 1996 (E) IEEE
Std. 1003.1,1996 [Incorporating ANSI/IEEE Stds 1003.1-1990, 1003.1b-1993,
1003.1c-1995, and 1003.1i-1995.])
•
The previous standard, Draft 4 of the IEEE standard. (DCE Threads products
T5819 and T8403 adhere to the Draft 4 standard.)
The functions are grouped into the following tables:
•
Table E-1, Replaced or Renamed Thread Functions, on page E-3
•
Table E-2, Thread Functions With Changed Parameters, on page E-4
•
Table E-3, New Thread Functions, on page E-5
•
Table E-4, Thread Functions With Changes to Return Values Only, on page E-6
•
Table E-5, Thread Functions With Changes to Return Values Among Other
Changes, on page E-8
•
Table E-6, Thread Functions With Miscellaneous Changes, on page E-12
•
Table E-7, Thread Functions With No Changes, on page E-12
•
Table E-8, Thread Functions Not Supported in Standard POSIX Threads, on
page E-13
•
Table E-9, Optional Thread Functions Supported in Standard POSIX Threads, on
page E-15
