8. Language-Specific Services for the C Programming Language Manager¶

8.1. Introduction¶

The language-specific services for the C programming language manager is ...

The directives provided by the language-specific services for the C programming language manager are:

• setlocale - Set the Current Locale
• fileno - Obtain File Descriptor Number for this File
• fdopen - Associate Stream with File Descriptor
• flockfile - Acquire Ownership of File Stream
• ftrylockfile - Poll to Acquire Ownership of File Stream
• funlockfile - Release Ownership of File Stream
• getc_unlocked - Get Character without Locking
• getchar_unlocked - Get Character from stdin without Locking
• putc_unlocked - Put Character without Locking
• putchar_unlocked - Put Character to stdin without Locking
• setjmp - Save Context for Non-Local Goto
• longjmp - Non-Local Jump to a Saved Context
• sigsetjmp - Save Context with Signal Status for Non-Local Goto
• siglongjmp - Non-Local Jump with Signal Status to a Saved Context
• tzset - Initialize Time Conversion Information
• strtok_r - Reentrant Extract Token from String
• asctime_r - Reentrant struct tm to ASCII Time Conversion
• ctime_r - Reentrant time_t to ASCII Time Conversion
• gmtime_r - Reentrant UTC Time Conversion
• localtime_r - Reentrant Local Time Conversion
• rand_r - Reentrant Random Number Generation
