LOADFIRMWARE(9) Kernel Developer's Manual LOADFIRMWARE(9)

loadfirmwareload a firmware file from the filesystem

#include <sys/device.h>

int
loadfirmware(const char *filename, u_char **buf, size_t *buflen);

The loadfirmware() function loads a firmware from the file specified by filename in the directory /etc/firmware. Memory for the firmware is allocated using malloc(9) with type M_DEVBUF as need be, within a reasonable size limit.

If no longer needed, the firmware buffer buf can be freed using free(9) with type M_DEVBUF.

If successful, buf is set to point to the allocation and buflen is set to the size of the firmware. Then loadfirmware() returns 0. Otherwise, it returns an errno style error.
