Name

Fstrerror(), Fstrerror32() - get error message string for FML error

Synopsis

#include <fml.h> 
 
char * 
Fstrerror(int err) 
 
#include <fml32.h> 
 
char *
Fstrerror32(int err)

Description

Fstrerror() is used to retrieve the text of an error message from LIBFML_CAT. err is the error code set in F_error when a FML function call returns a -1 or other failure value.

The user can use the pointer returned by Fstrerror() as an argument to userlog() or F_error.

Fstrerror32() is used with 32-bit FML.

A thread in a multithreaded application may issue a call to Fstrerror() or Fstrerror32() while running in any context state, including TPINVALIDCONTEXT.

Return Values

If err is an invalid error code, Fstrerror() returns a NULL. On success, the function returns a pointer to a string that contains the error message text.

Errors

Fstrerror() returns a NULL on error, but does not set F_error.
