C Standard Library

Call from the C standard library.

calloc(num::Integer, size::Integer) -> Ptr{Cvoid}

Call calloc from the C standard library.

Base.Libc.realloc — Function

realloc(addr::Ptr, size::Integer) -> Ptr{Cvoid}

Call realloc from the C standard library.

See warning in the documentation for regarding only using this on memory originally obtained from malloc.

Base.Libc.free — Function

Call free from the C standard library. Only use this on memory obtained from , not on pointers retrieved from other C libraries. Ptr objects obtained from C libraries should be freed by the free functions defined in that library, to avoid assertion failures if multiple libc libraries exist on the system.

Base.Libc.errno — Function

Get the value of the C library’s errno. If an argument is specified, it is used to set the value of errno.

Base.Libc.strerror — Function

Convert a system call error code to a descriptive string

Base.Libc.GetLastError — Function

GetLastError()

Call the Win32 GetLastError function [only available on Windows].

Base.Libc.FormatMessage — Function

Convert a Win32 system call error code to a descriptive string [only available on Windows].

Base.Libc.time — Method

Converts a TmStruct struct to a number of seconds since the epoch.

Base.Libc.strftime — Function

strftime([format], time)

Base.Libc.strptime — Function

strptime([format], timestr)

Parse a formatted time string into a TmStruct giving the seconds, minute, hour, date, etc. Supported formats are the same as those in the standard C library. On some platforms, timezones will not be parsed correctly. If the result of this function will be passed to time to convert it to seconds since the epoch, the isdst field should be filled in manually. Setting it to -1 will tell the C library to use the current system settings to determine the timezone.

Base.Libc.TmStruct — Type

Convert a number of seconds since the epoch to broken-down format, with fields , min, hour, mday, month, year, wday, yday, and isdst.

Base.Libc.flush_cstdio — Function

Flushes the C stdout and stderr streams (which may have been written to by external C code).

Base.Libc.systemsleep — Function

systemsleep(s::Real)

Suspends execution for s seconds. This function does not yield to Julia’s scheduler and therefore blocks the Julia thread that it is running on for the duration of the sleep time.
