_is_fat32

Syntax

#include <dos.h> int _is_fat32( const int drive );

Description

This function checks if drive number drive (1 == A:, 2 == B:, etc.) is formatted with FAT32.

For performance reasons the result is cached, hence if a drive is reformatted either from or to FAT32 a DJGPP program must be restarted.

Return Value

1 if the drive is formatted with FAT32, otherwise 0.

Portability

ANSI/ISO C	No
POSIX	No

Example

#include <stdio.h> #include <dos.h> int main(void) { if( _is_fat32( 'C' - 'A' + 1 ) ) { printf("C: is a FAT32 drive.\n"); } else { printf("C: is not a FAT32 drive.\n"); } exit(0); }
