NAME

       afOpenFile - open an audio file and create a file handle structure used for subsequent calls to the Audio File Library

SYNOPSIS

       #include <audiofile.h>

       AFfilehandle afOpenFile(const char *path, const char *mode,
	   AFfilesetup setup);

PARAMETERS

       path is the path to the file to be opened.

       mode specifies a mode for opening the file: "r" for reading or "w" for writing.

       setup is an AFfilesetup created by afNewFileSetup(3). This value is ignored for files opened for reading except when the file format is
       AF_FILE_RAWDATA.

RETURN VALUE

       Upon success, afOpenFile returns a valid AFfilehandle which can be used in subsequent calls to the Audio File Library. Upon failure,
       afOpenFile returns NULL and generates an error.

       afCloseFile(3) is used to close the file when it is no longer needed.

       afOpenFile can produce the following errors:

       AF_BAD_OPEN
