If a function is used without header, put the function code in your script before calling it.

== The Function Description==

<highlight-nsis>

Based on the method to loop over a buffer of null-terminated strings in function "GetDrives"

Loop over all available sections in an INI file.

Syntax:
${GetSectionNames} "File" "Function"

"File" ; name of the initialization file
"Function" ; Callback function then found

Function "Function"
; $9 "section name"
; $R0-$R9 are not used (save data in them).

; ...

Push $var ; If $var="StopGetSectionNames" Then exit from function
FunctionEnd
</highlight-nsis>

<b>Example1:</b>
<highlight-nsis>
Section
${GetSectionNames} "c:\test.ini" "Example1"
SectionEnd

Function Example1
MessageBox MB_OK "$9"

Push $0
FunctionEnd
</highlight-nsis>

<b>Example2:</b>
<highlight-nsis>
Section
${GetSectionNames} "c:\test.ini" "Example2"
SectionEnd

Function Example2
StrCmp $9 $R0 0 +3
StrCpy $R1 $9
StrCpy $0 StopGetSectionNames

Push $0
FunctionEnd
</highlight-nsis>

== The Function Code==
