SYNOPSYS¶
#include "mut.h"
char ∗namefind(inputname)
char ∗inputname;
PARAMETER¶
- inputname
- Pointer to a string of characters
DESCRIPTION¶
The
namefind function search the mbk dictionnary of names. If the string
has already been inserted in the dictionnary, then a pointer to this string is
return, else
namefind returns NULL.
The case of the letters do not matter. All names are changed to lower case
before beeing searched in the symbol table. This is needed because most of the
file format do not check case.
namefind is used by all mbk utility function using names, so its use
should be needed only when directly filling or modifing the structure, or when
having to compare an external string to mbk internal ones. This should speed
up string comparisons.
One shall never modify the contains of a string pointed to by a result of
namefind, since all the field that points to this name would have there
values modified, and that there is no chance that the new hash code will be
the same as the old one, so pointer comparison would be meaningless. All
string used by
namefind are constants string, and therefore must be
left alone.
RETURN VALUE¶
namefind returns a string pointer if the
inputname is already in
the hash table, else NULL.
EXAMPLE¶
#include "mut.h"
#include "mlo.h"
lofig_list ∗find_fig(name)
char ∗name;
{
lofig_list ∗p;
name = namefind(name);
if (name == NULL)
return NULL;
for (p = HEAD_LOFIG; p; p = p->NEXT)
if (p->NAME == name) /∗ pointer equality ∗/
return p;
return NULL;
}
DIAGNOSTICS¶
namefind can be used only after a call to
mbkenv(3).
