TAB(3)C LIBRARY FUNCTIONSTAB(3)

NAME

tab - simple table lookup routines

SYNOPSIS

#include <ast.h>

int tabindex(const void* tab, int size, const char* name); void* tablook(const void* tab, int size, const char* name);

DESCRIPTION

These routines do linear lookups in small tables (on the order of 32 elements). Each table element has a size of size bytes and the beginning of the element points to a name that is matched by the lookup routines.

tabindex returns the index of the table element in tab that matches name. If there is no match then -1 is returned.

tablook returns a pointer to the table element in tab that matches name. If there is no match then 0 is returned.
