Modules
	Benchmark
	These functions allow you to add a benchmark framework to a project for timing critical parts and detecting slow parts of code.
	Bezier Curve
	Convert
	These functions allow you to convert integer or real numbers to string or conversely.
	Counter
	This group discusses the functions that allow you to get the time spent in a part of a code.
	Copy On Write
	These functions provide some helper for a pseudo Copy-On-Write mechanism.
	Cpu
	Cpu and architecture related helpers.
	Error
	This group discusses the functions that provide error management for projects.
	File
	This group discusses the functions to handle files and directories.
	Lazy allocator
	Lock
	This group provides thread locking and synchronization capabilities.
	Log
	Full-featured logging system.
	Magic
	Eina_Magic provides run-time type-checking.
	Memory Pool
	This group discusses the functions that provide memory pool management.
	Module
	These functions provide module management.
	Prefix
	This group discusses the functions that provide the ability to determine the runtime location of a software package.
	Rectangle
	These functions provide rectangle management.
	Safety Checks
	Safety checks are a set of macros to check for parameters or values that should never happen, it is similar in concept to assert(), but will log and return instead of abort() your program.
	Simple_XML
	Simplistic relaxed SAX-like XML parser.
	String
	Provides useful functions for C string manipulation.
	Thread
	Abstracts platform threads, providing a uniform API.
	Xattrs
	Extended Attributes handling.

Function Documentation

eina_environment_home_get()

EINA_API const char * eina_environment_home_get

(

void

)

Returns the content of the environment referred by HOME on this system.

Returns

A temporary string to the content referred by HOME on this system.

Note

The result of this call is highly system dependent and you better use it instead of the naive getenv("HOME").

eina_environment_tmp_get()

EINA_API const char * eina_environment_tmp_get

(

void

)

Returns the content of the environment referred as TMPDIR on this system.

Returns

A temporary string to the content referred by TMPDIR on this system.

Note

The result of this call is highly system dependent and you better use it instead of the naive getenv("TMPDIR").
