Symbolic constants for -functions can be found in the header \fB<sys/syscall.h>\fR. -.SH RETURN VALUES -.sp -.LP -On error \fBsyscall()\fR returns \(mi1 and sets the external variable -\fBerrno\fR (see \fBIntro\fR(2)). -.SH FILES -.sp -.LP -\fB<sys/syscall.h>\fR -.SH SEE ALSO -.sp -.LP -\fBIntro\fR(2), \fBpipe\fR(2) -.SH NOTES -.sp -.LP -Use of these interfaces should be restricted to only applications written on -BSD platforms. Use of these interfaces with any of the system libraries or in -multi-thread applications is unsupported. -.SH WARNINGS -.sp -.LP -There is no way to use \fBsyscall()\fR to call functions such as \fBpipe\fR(2) -which return values that do not fit into one hardware register. -.sp -.LP -Since many system calls are implemented as library wrappers around traps to the -kernel, these calls may not behave as documented when called from -\fBsyscall()\fR, which bypasses these wrappers. For these reasons, using -\fBsyscall()\fR is not recommended. |
