16 GPIO_GET_LINEHANDLE_IOCTL - Request a line or lines from the kernel.
55 .. _gpio-get-linehandle-config-rules:
58 -------------------
65 line is requested "as-is" to allow reading of the line value without altering
71 If none are set then the line is assumed push-pull.
80 .. _gpio-get-linehandle-config-support:
83 ---------------------
86 hardware and driver, the kernel applies one of these approaches:
88 - reject the request
89 - emulate the feature in software
90 - treat the feature as best effort
93 in software, and the impact on the hardware and userspace if the feature is not
111 be driven.
113 In all cases, the configuration reported by gpio-get-lineinfo-ioctl.rst
114 is the requested configuration, not the resulting hardware configuration.
115 Userspace cannot determine if a feature is supported in hardware, is
124 On error -1 and the ``errno`` variable is set appropriately.
125 Common error codes are described in error-codes.rst.
