The HP ANSI C compiler now defines the predefined identifier__func__, as specified in the C9X Standard. It has been added
to HP C to provide you with additional means of debugging your code.
Syntax |
 |
The __func__ identifier is implicitly declared by the compiler
in the following manner:
static const char __func__[ ] = "<function-name>"; |
The above declaration is implicitly added immediately after
the opening brace of a function which uses the variable __func__. The value <function-name> is
the name of hte lexically-enclosing function. This name is the unadorned
name of the function.
Example |
|
The following code example fragment illustrates the use of predefined identifier__func__.
#include <stdio.h>
void varfunc(void)
{
printf("%s\n", __func__);
/* ... */
} |
Each time the varfunc function is called, it prints to the
standard output stream:
