.TH LIBSIMPLE_MEMRCHR 3 libsimple .SH NAME libsimple_memrchr \- find byte in memory .SH SYNOPSIS .nf #include void *libsimple_memrchr(const void *\fIs\fP, int \fIc\fP, size_t \fIn\fP); #ifndef memrchr # define memrchr libsimple_memrchr #endif .fi .PP Link with .IR \-lsimple . .SH DESCRIPTION The .BR libsimple_memrchr () function scans the memory segment .IR s , with the size .IR n , for the last occurence of the byte .I c (it is converted to a .BR char ). .PP The comparison is case-sensitive. .SH RETURN VALUE The .BR libsimple_memrchr () function returns the pointer .I s with a maximal offset such that .IR *r==c , where .I r is the returned pointer. If no such offset exists, .B NULL is returned. .SH ERRORS The .BR libsimple_memrchr () function cannot fail. .SH ATTRIBUTES For an explanation of the terms used in this section, see .BR attributes (7). .TS allbox; lb lb lb l l l.
