Language Environment both z/OS V1R2 or later

Syntax

#include <ctype.h>

void __ae_thread_setmode(int aemode);

General description

The __ae_thread_setmode() function sets the current thread's character mode to ASCII or EBCDIC based on the value of the argument aemode:
  • __AE_ASCII_MODE - set thread character mode to ASCII
  • __AE_EBCDIC_MODE - set thread character mode to EBCDIC

If the value for aemode is other than the values shown above, the thread's ASCII/EBCDIC mode will remain unchanged.

The TCP/IP resolver is reinitialized, if already initialized, in the new character mode. This function or __ae_thread_swapmode() must be used before and after calls between EBCDIC and ASCII portions of an application.

Return values

If successful, __ae_thread_setmode() changes the character mode.

If unsuccessful, __ae_thread_setmode() will terminate with either message EDC6254 or EDC6255.

There are no documented errnos for this function.
