SYSCALL(2) BSD System Calls Manual SYSCALL(2) NAME syscall -- indirect system call SYNOPSIS #include <sys/syscall.h> #include <unistd.h> int syscall(int number, ...); DESCRIPTION Syscall() performs the system call whose assembly language interface has the specified number with the specified arguments. Symbolic constants for system calls can be found in the header file <sys/syscall.h>. This function is useful for testing new system calls that do not have entries in the C library. RETURN VALUES The return values are defined by the system call being invoked. In general, a 0 return value indicates success. A -1 return value indicates an error, and an error code is stored in errno. BUGS There is no way to simulate system calls that have multiple return values such as pipe(2). HISTORY The syscall() function call appeared in 4.0BSD. 4th Berkeley Distribution June 23, 2008 4th Berkeley Distribution |
