/* NAME
/* attr 3
/* SUMMARY
/* attribute list manager
/* simple attribute list manager
/* SYNOPSIS
/* #include <htable.h>
/* #include <attr.h>
/*
/* void attr_enter(attr, name, value)
/* HTABLE *attr;
/* void attr_enter(table, flags, name, value, ..., (char *) 0)

/* int flags;
/* const char *name;

/* HTABLE *attr;
/* const char **vptr;
/* DESCRIPTION
/* This module maintains open attribute lists of string-valued
/* names and values. The module is built on top of the generic
/* htable(3) hash table manager.
/*
/* attr_enter() adds a new attribute or updates an existing one.
/* Both the name and the value are copied.
/* attr_enter() adds or updates zero or more attribute-value pairs.
/* Both the name and the value are copied. The argument list is
/* terminated with a null character pointer.
/*
/* attr_find() looks up the named attribute. It returns the
/* corresponding value if one is found, a null pointer otherwise.
/* attr_find() looks up zero or more named attribute values. The
/* result value is the number of attributes found; the search
/* stops at the first error. The values are not copied out; it
/* is up to the caller to save copies of values where needed.
/*
/* attr_free() destroys the named attribute list and makes its
/* memory available for reuse.
/* BUGS
/* This module cannot store null pointer values. If that is a
/* problem, use the raw hash table management routines instead.
/* Arguments:
/* .IP table
/* Pointer to hash table.
/* .IP flags
/* Bit-wise OR of the following:
/* .RS
/* .IP ATTR_FLAG_MISSING
/* Log a warning when attr_find() cannot find an attribute. The
/* search always terminates when a request cannot be satisfied.
/* .IP ATTR_FLAG_EXTRA
/* Log a warning and return immediately when attr_enter() finds
/* that a specified attribute already exists in the table.
/* By default, attr_enter() replaces an existing attribute value
/* by the specified one.
/* .IP ATTR_FLAG_NONE
/* For convenience, this value requests none of the above.
/* .RE
/* .IP name
/* Attribute name. Specify a null character pointer to terminate
/* the argument list.
/* .IP value
/* Attribute value. attr_enter() makes a copy.
/* .IP vptr
/* Pointer to character pointer. attr_find() makes no copy of the
/* value.

/* NAME
/* attr_table 3
/* SUMMARY
/* recover attributes from byte stream
/* SYNOPSIS
/* #include <attr.h>
/*
/* ATTR_TABLE *attr_table_create(size)
/* int size;
/*
/* void attr_table_free(attr)
/* ATTR_TABLE *attr;
/*
/* int attr_table_read(attr, flags, fp)
/* ATTR_TABLE *attr;

/* ATTR_TABLE *attr;
/* int flags;
/* int type;
/* char *name;
/* DESCRIPTION
/* This module provides an alternative process for recovering
/* attribute lists from a byte stream. The process involves the
/* storage in an intermediate attribute table that is subsequently
/* queried. This procedure gives more control to the application,
/* at the cost of complexity and of memory resources.
/*
/* attr_table_create() creates an empty table for storage of
/* the intermediate result from attr_table_read().
/*
/* attr_table_free() destroys its argument.
/*
/* attr_table_read() reads an attribute list from a byte stream
/* and stores the intermediate result into a table that can be
/* queried with attr_table_get().
/*
/* attr_table_get() takes zero or more (name, value) scalar or array
/* attribute arguments, and recovers the attribute values from the
/* intermediate attribute table produced by attr_table_read().
/*
/* Arguments:
/* .IP fp
/* Stream to recover the attributes from.
/* .IP flags
/* The bit-wise OR of zero or more of the following.
/* .RS
/* .IP ATTR_FLAG_MISSING
/* Log a warning when the input attribute list terminates before all
/* requested attributes are recovered. It is always an error when the
/* input stream ends without the newline attribute list terminator.
/* This flag has no effect with attr_table_read().
/* .IP ATTR_FLAG_EXTRA
/* Log a warning and stop attribute recovery when the input stream
/* contains multiple instances of an attribute.
/* This flag has no effect with attr_table_get().
/* .IP ATTR_FLAG_NONE
/* For convenience, this value requests none of the above.
/* .RE
/* .IP type
/* The type determines the arguments that follow.
/* .RS
/* .IP "ATTR_TYPE_NUM (char *, int *)"
/* This argument is followed by an attribute name and an integer pointer.
/* This is used for recovering an integer attribute value.
/* .IP "ATTR_TYPE_STR (char *, VSTRING *)"
/* This argument is followed by an attribute name and a VSTRING pointer.
/* This is used for recovering a string attribute value.
/* .IP "ATTR_TYPE_NUM_ARRAY (char *, INTV *)"
/* This argument is followed by an attribute name and an INTV pointer.
/* This is used for recovering an integer array attribute value.
/* .IP "ATTR_TYPE_NUM_ARRAY (char *, ARGV *)"
/* This argument is followed by an attribute name and an ARGV pointer.
/* This is used for recovering a string array attribute value.
/* .IP ATTR_TYPE_END
/* This terminates the requested attribute list.
/* .RE
/* DIAGNOSTICS
/* The result value from attr_table_read() and from attr_table_get()
/* is the number of attributes that were successfully recovered from
/* the input stream (an array-valued attribute counts as one attribute).
/*
/* Panic: interface violation. All system call errors are fatal.
/* SEE ALSO
/* attr_print(3) send attributes over byte stream.
