Hello! I have one wav file need to read. The header has 44 bytes: 37-40 bytes contains "data" and 41-44 contains the size of data chunk. So:
Code: Select all
int fp = sceIoOpen(segmentoElegido, PSP_O_RDONLY, 0777);
sceIoRead(fp,dheader,36);
char data[5];
sceIoRead(fp,data,4);
printf("\ndata = %#x", data[0]);
printf("\ndata = %#x", data[1]);
printf("\ndata = %#x", data[2]);
printf("\ndata = %#x", data[3]);
char size[5];
sceIoRead(fp,size,4);
printf("\ntamfich1 = %#x", size[0]);
printf("\ntamfich1 = %#x", size[1]);
printf("\ntamfich1 = %#x", size[2]);
printf("\ntamfich1 = %#x", size[3]);
If the byte doesn´t begin with a letter (ie 0x90) it prints the byte ok (0x90) but if begins with a letter (ie 0xa0) it prints 0xffffffa0.
Has anybody had this problem?
Thanks :)

Use u8 (or unsigned char) instead of chars.
