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 to 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 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.
