pbuf_memcmp() function

Compare pbuf contents at specified offset with memory s2, both of length n

Syntax

u16_t pbuf_memcmp(const struct pbuf* p,     u16_t offset,     const void* s2,     u16_t n);
Implemented in pbuf.c:1433

Arguments

p

pbuf to compare

offset

offset into p at which to start comparing

s2

buffer to compare

n

length of buffer to compare

Return value

zero if equal, nonzero otherwise (0xffff if p is too short, diffoffset+1 otherwise)
