Description

The INI_GET() function returns the value from an individual key in a specified section of an 'ini' file. The value is returned as a character string.


Parameter Description
<expC1> Name of the section.
<expC2> Name of the key.
<expC3> Default value to return if key does not exist.
<expC4> Name of the ini file.
<expL> .T. to expand macros, .F. to return macros without expanding. If this optional parameter is not included, macro expansion defaults to .F. (false).


Example

# test.ini
# comment lines are preceeded by a '#' 
; or a ';'
#
# "Sections" are enclosed in [ and ]
[global]
; key/value pairs are contained in the sections and are written like this
 	key1 = value
 	key2 = value2
; You can include macros in the key/value pairs.
 	key3 = This is $(key2) and $(key1)
# end of test.ini
key1value = ini_get('global','key1','unset','test.ini',.T.)
