SetupFindFirstLineA function (setupapi.h)
[This function is available for use in the operating systems indicated in the Requirements section. It may be altered or unavailable in subsequent versions. SetupAPI should no longer be used for installing applications. Instead, use the Windows Installer for developing application installers. SetupAPI continues to be used for installing device drivers.]
The SetupFindFirstLine function locates a line in the specified section of an INF file. If the Key parameter is NULL, SetupFindFirstLine returns the first line of the section.
Syntax
WINSETUPAPI BOOL SetupFindFirstLineA(
[in] HINF InfHandle,
[in] PCSTR Section,
[in] PCSTR Key,
[in, out] PINFCONTEXT Context
);
Parameters
[in] InfHandle
Handle to the INF file to query.
[in] Section
Pointer to a null-terminated string specifying the section of the INF files to search in.
[in] Key
Optional pointer to a null-terminated string specifying the key to search for within the section. The null-terminated string should not exceed the size of the destination buffer. This parameter can be NULL. If Key is NULL, the first line in the section is returned.
[in, out] Context
Pointer to a structure that receives the context information used internally by the INF handle. Applications must not overwrite values in this structure.
Return value
If the function could not find a line, the return value is zero. To get extended error information, call GetLastError.
Remarks
If the InfHandle parameter references multiple INF files that have been appended together using SetupOpenAppendInfFile, the SetupFindFirstLine function searches across the specified section in all of the files referenced by the specified HINF.
Note
The setupapi.h header defines SetupFindFirstLine as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
