properties_read, property_find, properties_free – functions to allow creating simple property lists from ASCII file data

LIBRARY SYNOPSIS DESCRIPTION FILE FORMAT AUTHORS BUGS

System Utilities Library (libutil, -lutil)

#include <libutil.h>

properties
properties_read(int fd);

char *
property_find(properties list, const char *name);

void
properties_free(properties list);

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

The function properties_read() reads name, =, value pairs from the file descriptor passed in 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 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.

Each property in the file is assumed to have the format of name, =, value where name is an alphanumeric string (and any punctuation not including the `=' character) and value is an arbitrary 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.
