afOpenFile - open an audio file and create a file handle structure used for subsequent calls to the Audio File Library
#include <audiofile.h> AFfilehandle afOpenFile(const char *path, const char *mode, AFfilesetup setup);
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.
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 A call to open failed. AF_BAD_READ A call to read failed AF_BAD_WRITE A call to write failed. AF_BAD_LSEEK A call to lseek failed. AF_BAD_MALLOC Memory allocation failed. AF_BAD_FILEFMT setup specifies a file format which is unsupported for mode. AF_BAD_SAMPFMT The file’s sample format is not supported. AF_BAD_WIDTH The file’s sample width is not supported. AF_BAD_RATE The file’s sample rate is not supported. AF_BAD_CHANNELS The number of channels in the file is not supported. AF_BAD_FILESETUP setup specifies an invalid or unsupported configuration.
