snd_strerror()

Convert an error code to a string

Synopsis:

#include <sys/asoundlib.h>

const char *snd_strerror( int errnum );

Arguments:

errnum: An error number, which can be positive (i.e., the value of errno) or negative (i.e., a return code from a snd_* function).

Library:

libasound.so

Use the -l asound option with qcc to link against this library.

Description:

The snd_strerror() function converts an error code to a string. Its functionality is similar to that of strerror() (see the QNX Neutrino C Library Reference), except that it returns the correct strings for sound error codes.

Returns:

A pointer to the error message. Don't modify the string that it points to.

If snd_strerror() doesn't recognize the value for errnum, it returns a pointer to the string “Unknown error.”

Examples:

See the wave.c example in the appendix.
