Detailed Description

This handles abstract system level calls.

Function Documentation

◆ SYS_InitRandom()

INTERNAL void SYS_InitRandom ( void )

Initialize the random generator.

Definition at line 136 of file sys_unix.c.

◆ SYS_RandomInt()

INTERNAL int SYS_RandomInt ( void )

Generate a pseudo random number.

Returns: a non-negative random number

Remarks: the range is at least up to 2^31.; this is a CSPRNG when getrandom() is available, LCG otherwise.

Warning: SYS_InitRandom() should be called (once) before using this function.; not thread safe when system lacks getrandom() syscall.; not cryptographically secure when system lacks getrandom() syscall.; if interrupted by a signal, this function may return 0.

Definition at line 106 of file sys_unix.c.

◆ SYS_Sleep()

INTERNAL int SYS_Sleep ( int iTimeVal )

Makes the current process sleep for some seconds.

Parameters

[in] iTimeVal Number of seconds to sleep.

Definition at line 60 of file sys_unix.c.

◆ SYS_USleep()

INTERNAL int SYS_USleep ( int iTimeVal )

Makes the current process sleep for some microseconds.
