PROPERTIES(3) BSD Library Functions Manual PROPERTIES(3)NAME
properties_read, property_find, properties_free -- functions to allow creating simple property lists from ASCII file data
LIBRARY
System Utilities Library (libutil, -lutil)
SYNOPSIS
#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 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.
FILE FORMAT
Each property in the file is assumed to have the format of name = value where name is an alphanumeric string (and any punctuation not includ-
ing 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.

XkbAddGeomProperty(3) XKB FUNCTIONS XkbAddGeomProperty(3)NAME
XkbAddGeomProperty - Add one property to an existing keyboard geometry description
SYNOPSIS
XkbPropertyPtr XkbAddGeomProperty (XkbGeometryPtr geom, char *name, char *value);
ARGUMENTS
- geom geometry to be updated
- name name of the new property
- value
value for the new property
DESCRIPTION
Xkb provides functions to add a single new element to the top-level keyboard geometry. In each case the num_ * fields of the corresponding
structure is incremented by 1. These functions do not change sz_* unless there is no more room in the array. Some of these functions fill
in the values of the element's structure from the arguments. For other functions, you must explicitly write code to fill the structure's
elements.
The top-level geometry description includes a list of geometry properties. A geometry property associates an arbitrary string with an
equally arbitrary name. Programs that display images of keyboards can use geometry properties as hints, but they are not interpreted by
Xkb. No other geometry structures refer to geometry properties.
XkbAddGeomProperty adds one property with the specified name and value to the keyboard geometry specified by geom. XkbAddGeomProperty
returns NULL if any of the parameters is empty or if it was not able to allocate space for the property. To allocate space for an arbitrary
number of properties, use the XkbAllocGeomProps function.
STRUCTURES
typedef struct _XkbProperty {
char * name; /* property name */
char * value; /* property value */
} XkbPropertyRec,*XkbPropertyPtr;

Introduction
I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.
main()

malloc(1gb)
return(0)
}
The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)
I see lot of ad-hoc shell scripts in our servers which don't have a shebang at the beginning .
Does this mean that it will run on any shell ?
Is it a good practice to create scripts (even ad-hoc ones) without shebang ? (16 Replies)
