is_selinux_enabled – check whether SELinux is enabled Nameis_selinux_mls_enabled – check whether SELinux is enabled for (Multi Level Security) MLS Synopsis#include <selinux/selinux.h> int is_selinux_enabled(); int is_selinux_mls_enabled(); Descriptionis_selinux_enabled() returns 1 if SELinux is running or 0 if it is not. On error, -1 is returned. is_selinux_mls_enabled() returns 1 if SELinux is capable of running in MLS mode…

is_relative_filename – Returns TRUE if the filename is relative. Allegro game programming library. Synopsis#include <allegro.h> int is_relative_filename(const char *filename); DescriptionReturns TRUE if the filename is relative or FALSE if it is absolute. Note that an absolute filename under DOS (with a device separator) will be considered as relative under Unix, because there absolute paths always…

is_memory_bitmap – Tells if a bitmap is a memory bitmap. Allegro game programming library. Synopsis#include <allegro.h> int is_memory_bitmap(BITMAP *bmp); DescriptionReturns TRUE if bmp is a memory bitmap, ie. it was created by calling create_bitmap() or loaded from a grabber datafile or image file. Memory bitmaps can be accessed directly via the line pointers in the…

is_linear_bitmap – Tells if a bitmap is linear. Allegro game programming library. Synopsis#include <allegro.h> int is_linear_bitmap(BITMAP *bmp); DescriptionReturns TRUE if bmp is a linear bitmap, i.e. a bitmap that can be accessed linearly within each scanline (for example a memory bitmap, the DOS VGA or SVGA screen, Windows bitmaps, etc). Linear bitmaps can be used…

is_inside_bitmap – Tells if a point is inside a bitmap. Allegro game programming library. Synopsis#include <allegro.h> int is_inside_bitmap(BITMAP *bmp, int x, int y, int clip); DescriptionReturns non-zero if point (x, y) lies inside the bitmap. If `clip’ is non-zero, the function compares the coordinates with the clipping rectangle, that is it returns non-zero if the…

is_context_customizable – check whether SELinux context type is customizable by the administrator Synopsis#include <selinux/selinux.h> int is_context_customizable(char *scon); DescriptionThis function checks whether the type of scon is in the /etc/selinux/{SELINUXTYPE}/context/customizable_types file. A customizable type is a file context type that administrators set on files, usually to allow certain domains to share the file content. restorecon and…

is_compatible_font – Check if two fonts are of the same type. Allegro game programming library. Synopsis#include <allegro.h> int *is_compatible_font(FONT *f1, FONT *f2) DescriptionThis function compares the two fonts, which you can use to find out if Allegro is capable of merging them. Return ValueReturns TRUE if the two fonts are of the same general type…
