SETLABEL 3C "June 19, 2021"
NAME
setlabel - define the label for pfmt() and lfmt()
SYNOPSIS
#include <pfmt.h>

int setlabel(const char *label);
DESCRIPTION
The setlabel() function defines the label for messages produced in standard format by subsequent calls to lfmt(3C) and pfmt(3C).

The label argument is a character string no more than 25 characters in length.

No label is defined before setlabel() is called. The label should be set once at the beginning of a utility and remain constant. A null pointer or an empty string passed as argument will reset the definition of the label.

RETURN VALUE
Upon successful completion, setlabel() returns 0; otherwise, it returns a non-zero value.
EXAMPLES
The following code (without previous call to setlabel()):
pfmt(stderr, MM_ERROR, "test:2:Cannot open file\en");
setlabel("UX:test");
pfmt(stderr, MM_ERROR, "test:2:Cannot open file\en");

will produce the following output:

ERROR: Cannot open file
UX:test: ERROR: Cannot open file
