    NAME

    properties_read
    
     
    propery_find
    
     
    properties_free
    
     - functions to allow creating simple property lists from ASCII file data
    
     
    

    LIBRARY

    Lb libutil
    
     
    

    SYNOPSIS

       #include <sys/types.h>
       #include <libutil.h>
    properties properties_read (int fd);
    char * property_find (properties list const char *name);
    void properties_free (properties list);
     

    DESCRIPTION

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

    The function 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_find ();
    function returns the associated value string for the property named Fa name if found, otherwise NULL. The value returned may be up to PROPERTY_MAX_VALUE bytes in length.

    The properties_free ();
    function is used to free the structure returned by properties_read ();
    when it is no longer needed.  

    FILE FORMAT

    Each property in the file is assumed to have the format of Fa name = value where Fa name is an alphanumeric string (and any punctuation not including the `=' character) and Fa value is an arbitary string of text terminated by a newline character. If newlines are desired, the entire value should be enclosed in { } (curly-bracket) characters. Any line beginning with a # or ; character is assumed to be a comment and will be ignored.
