SYNOPSIS

#include <prof_attr.h>

profattr_t *getprofattr(void);


profattr_t *getprofnam(const char *name);


void free_profattr(profattr_t *pd);


void setprofattr(void);


void endprofattr(void);


void getproflist(const char *profname, char **proflist, int *profcnt);


void free_proflist(char **proflist, int profcnt);


DESCRIPTION


The getprofattr() and getprofnam() functions each return a prof_attr
entry. Entries can come from any of the sources specified in the
nsswitch.conf(4) file.


The getprofattr() function enumerates prof_attr entries. The getprofnam()
function searches for a prof_attr entry with a given name. Successive
calls to these functions return either successive prof_attr entries or
NULL.


The internal representation of a prof_attr entry is a profattr_t
structure defined in <prof_attr.h> with the following members:

char *name; /* Name of the profile */
char *res1; /* Reserved for future use */
char *res2; /* Reserved for future use */
char *desc; /* Description/Purpose of the profile */
kva_t *attr; /* Profile attributes */


The free_profattr() function releases memory allocated by the
getprofattr() and getprofnam() functions.


The setprofattr() function "rewinds" to the beginning of the enumeration
of prof_attr entries. Calls to getprofnam() can leave the enumeration in
an indeterminate state. Therefore, setprofattr() should be called before
the first call to getprofattr().


The endprofattr() function may be called to indicate that prof_attr
processing is complete; the system may then close any open prof_attr
file, deallocate storage, and so forth.


The getproflist() function searches for the list of sub-profiles found in
the given profname and allocates memory to store this list in proflist.
The given profname will be included in the list of sub-profiles. The
profcnt argument indicates the number of items currently valid in
proflist. Memory allocated by getproflist() should be freed using the
free_proflist() function.


The free_proflist() function frees memory allocated by the getproflist()
function. The profcnt argument specifies the number of items to free
from the proflist argument.

RETURN VALUES


The getprofattr() function returns a pointer to a profattr_t if it
successfully enumerates an entry; otherwise it returns NULL, indicating
the end of the enumeration.


The getprofnam() function returns a pointer to a profattr_t if it
successfully locates the requested entry; otherwise it returns NULL.

USAGE


Individual attributes in the profattr_t structure can be referred to by
calling the kva_match(3SECDB) function.


Because the list of legal keys is likely to expand, any code must be
written to ignore unknown key-value pairs without error.


The getprofattr() and getprofnam() functions both allocate memory for the
pointers they return. This memory should be deallocated with the
free_profattr() function.
