Hello MISRA experts,
I have the following function implemented in one of the firmware libraries. However, I get MISRA 10.1 violation. I can’t understand what I’m doing wrong.
Can someone please help me on this?
int32_t audio_buffer_size = 0;
char *audio_buffer = (char *)NULL;
int32_t FileIF_CopyFileToBuffer(const char *filename, int32_t offset, char *buffer, int32_t *buf_size, int32_t *file_size);
int32_t SDCardIF_PlayAudioFile(const char *filename)
{
int32_t ret = SDCARD_IF_OP_SUCCESS;
int32_t amount_read = audio_buffer_size;
int32_t file_size = 0;
if(IsNotInitialized()){
ret = SDCARD_IF_ERR_NOT_INITIALIZED;
}
else if((NULL == audio_buffer) || (0 == audio_buffer_size)){
ret = SDCARD_IF_ERR_AUDIO_BUFFER_NOT_SET;
}
else{
ret = FileIF_CopyFileToBuffer(filename, 0, audio_buffer, &amount_read, &file_size); // MISRA warning!
}
return ret;
}
MISRA Error:
#1393-D (MISRA-C:2004 10.1/R) The value of an expression of integer type shall not be implicitly converted to a different underlying type if the expression is not constant and is a function argument
Thank you!
