.SH DESCRIPTION
To free possible data stored into an XpmImage structure use XpmFreeXpmImage.
The XpmFreeXpmImagefrees the structure members which are not NULL, but not the structure itself.
To free possible data stored into an XpmInfo structure use XpmFreeXpmInfo.
To free data possibly stored into an array of XpmExtension use XpmFreeExtensions.
To free any data allocated by an XPM function use the XpmFree function.
The current distribution of the XPM library uses the standard memory allocation functions and thus
XpmFree is nothing else than a define to the standard free.
However since these functions may be redefined in specific environments it is wise to use XpmFree.
To free possible data stored into an XpmAttributes structure use XpmFreeAtatributes.
The XpmFreeAttributes frees the structure members which have been malloc’ed such as the pixels list.
To dynamically allocate an XpmAttributes structure use the XpmAttributesSize function.
The XpmAttributesSize function provides application using dynamic libraries with a safe way to allocate and then
refer to an XpmAttributesstructure, disregarding whether the XpmAttributes structure size has changed or not since
compiled.
To get data when building an error message, one can use XpmGetErrorString.
XpmGetErrorString returns a string related to the given XPM error code.
The XpmLibraryVersion can be used when one needs to figure out which version of the library is in use.
The value returned by XpmLibraryVersion can be compared to the value of XpmIncludeVersion which is defined
in the header file "xpm.h". These numbers are computed with the following formula:
.nf
(XpmFormat * 100 + XpmVersion) * 100 + XpmRevision
.fi
Where XpmFormat is the version number of the format, XpmVersion is the library version number (which changes
only if the API changes), and XpmRevision is the library minor version number.
The XpmFreeExtensions function frees all data stored in every extension and the array itself.
Note that XpmFreeAttributes call this function and thus most of the time it should not need to be explicitly called.
