![]() I thought the data type FILE was defined in cs50.h? There is a similar error when I try to use sprintf() saying that I'm passing a pointer to a file to a parameter that is expecting a pointer to a character. ![]() So from what I can tell the program is telling me that I'm initializing the pointer to the FILE incorrectly while the file type should instead be an unsigned long. usr/include/stdio.h:320:38: note: passing argument to parameter '_s' hereĮxtern int sprintf (char *_restrict _s, Recoveredit.c:35:21: error: incompatible pointer types passing 'FILE *' (aka 'struct _IO_FILE *') to parameter of type Recoveredit.c:25:11: error: incompatible integer to pointer conversion initializing 'FILE *' (aka 'struct _IO_FILE *') with anĮxpression of type 'unsigned long' Upon trying to compile this program i get the following errors If (buffer = 0xff & buffer = 0xd8 & buffer = 0xff & (buffer & 0xf0) = 0xe0)įwrite(jpgwrit,sizeof(BYTE),512*i, writing) ![]() You can visit our channel on youtube for the whole playtlist. To fix this error, you need to ensure that the type of the value you are assigning to the pointer is compatible with the type of the pointer. Unsigned char bytes //create an array of unsigned characters with 4 slotsįILE *writing = fwrite(jpgwrit,sizeof(BYTE),512, File) In this tutorial, we explained the c compilation warning : initialization from incompatible pointer type.

When I try to pass in argv, i get the following warning. Hi I'm trying to pass in argv into a function that checks the arguments and assigns values for the arguments passed it. I'm still having trouble getting the program to even compile while passing different parameters to sprintf() and file pointers. How would I fix this incompatible pointer type warning. ![]() I've been working on recover for a very long time and making incremental gains. ![]()
