.Dd October 7, 1998 .Os .Dt properties 3 .Sh NAME .Nm properties_read , .Nm propery_find , .Nm properties_free .Nd functions to allow creating simple property lists from ascii file data. .Sh SYNOPSIS .Fd #include <sys/types.h> .Fd #include <libutil.h> .Ft properties .Fn properties_read "int fd" .Ft char * .Fn property_find "char *name" .Ft void .Fn properties_free "properties list"

p Link with .Va -lutil on the .Xr cc 1 command line. .Sh DESCRIPTION

typedef struct _properties {
 struct _properties *next;
 char *name;
 char *value;
} *properties;

The function .Fn properties_read reads .Fa name = value pairs from the file descriptor passed in .Fa fd and returns the head of a new property list, assuming that the file's contents have been parsed properly, or NULL in case of error. The property list pointer should be passed to .Fn properties_free when no longer needed.

p .Fn property_find Returns the associated value string for the property named .Fa name if found, otherwise NULL.

p .Fn properties_free is used to free the structure returned by .Fn properties_read when it is no longer needed. .Sh SEE ALSO .Xr auth_getval 3 .Sh BUGS Simplistic.
